    Myeloid sarcoma (MS) is a rare extramedullary myeloid tumour. It has been reported in various sites, including lymph node, bone, skin, soft tissue, various organs and the CNS. It may precede or occur concurrently with acute myeloid leukemia. Urinary bladder involvement is extremely uncommon. We report a 70-year-old female who had MS of the urinary bladder, presented with frank and persistent hematuria associated with lower abdominal pain. She subsequently had tumour seeding in the abdominal skin via percutaneous suprapubic catheter. Tumours from both the urinary bladder and skin showed immature cells that were immunoreactive toward LCA (focal), MPO (strong), CD99 (weak) and CD117 (weak). Summary of cases in the literature is presented. The potential of its misdiagnosis and the useful markers for the diagnosis of MS are discussed.

    Sundapolystoma chalconotae. n. g., n. sp. (Polystomatidae, Polystomatinae) is proposed for a new polystomatid from the urinary bladder of Rana chalconota (Schlegel) in Peninsular Malaysia. This is the first species of polystomatid to be described from the amphibians of Peninsular Malaysia and the second for the Southeast Asian region. This new genus, as exemplified by S. chalconotae, differs from other polystomatids, and in particular Parapolystoma Ozaki, 1935 (P. bulliense (Johnston, 1912) Ozaki, 1935 and P. johnstoni Pichelin, 1995), in having a tubular uterus and a single diffuse testis. P. crooki Vande Vusse, 1976 is similar to S. chalconotae in having a similar type of uterus and testis, and is re-assigned as Sundapolystoma crooki (Vande Vusse, 1976) n. comb. S. chalconotae differs from S. crooki in having anchors with a longer outer root rather than a longer inner root and 7-8 genital spines compared to 9-13 in S. crooki.

    The uroflow and pressure-flow data of 67 men aged 65 years or more were compared. At best, the uroflow study applying the Liverpool nomogram (25th percentile) and Bristol nomogram (OSD) diagnosed bladder outlet obstruction with sensitivity of 62.5% and 62.5% and specificity of 48.8% and 74.4% respectively. Using the 50th percentile of the Liverpool nomogram as the cut-off resulted in a negative predictive value of 100.0% allowing about 10% of men to have this diagnosis ruled out. We conclude that the uroflow study is inaccurate in diagnosing bladder outlet obstruction in elderly men. However, it can be used to rule out this condition in the small subset of men with maximum flow rates above the 50th percentile of the Liverpool nomogram.

    A case of primary non-Hodgkin's lymphoma of the terminal ileum with enterovesical fistula is reported. A 50-year-old Malay man presented with haematuria, dysuria and per-rectal bleeding. Intravenous urogram, double contrast enema and an MDP bone scintigram showed a fistulous communication between the bladder and distal ileum. At laparotomy, a large tumour attaching the terminal ileum to the dome of the bladder was found. Histopathological examination of resected small bowel revealed a diffuse histiocytic non-Hodgkin's lymphoma of the small bowel. The bladder mucosa was shown to be normal.

    A total of 62 patients with vesico-urethral dysfunction were investigated at the Urodynamic Laboratory (Universiti Kebangsaan Malaysia) at the Institute of Urology and Nephrology over a period of eleven months in 1985. In most instances the results significantly influenced a change in patient management strategy. These results are analysed and the usefulness and limitations of this modality of investigations are critically alluded to.

    INTRODUCTION: Neurogenic bladder (NB) is a recognized secondary medical impairment following spinal cord injury (SCI). Ultrasound (US) of the kidneys, ureters and bladder (KUB) has been recommended as a useful, non-invasive surveillance method with good diagnostic sensitivity. This study aims to understand US diagnosed NB complications and identify its associated factors.

    METHODS: We enrolled all patients referred for SCI rehabilitation from 2012 to 2015 that fulfilled our study criteria. Data that were retrospectively reviewed included demographic and clinical characteristic data; and US KUB surveillance studies.

    RESULTS: Out of 136 electronic medical records reviewed, 110 fulfilled the study criteria. The prevalence of NB in our study population was 80.9%. We found 22(20%) of the patients showed evidence of US diagnosed NB complications with the mean detection of 9.61±7.91 months following initial SCI. The reported NB complications were specific morphological changes in the bladder wall 8(36.4%); followed by unilateral/bilateral hydronephrosis 7(31.8%); bladder and/or renal calculi 5(22.7%); and mixed complication 2(9.1%) respectively. Half of the patients with NB complications had urodynamic diagnosis of neurogenic detrusor overactivity with/without evidence of detrusor sphincter dyssynergia. We found co-existing neurogenic bowel, presence of spasticity and mode of bladder management were significantly associated factors with US diagnosed NB complications (p<0.05), while spasticity was its predictor with adjusted Odds Ratio value of 3.93 (1.14, 13.56).

    CONCLUSION: NB is a common secondary medical impairment in our SCI population. A proportion of them had US diagnosed NB complications. Co-existing neurogenic bowel, presence of spasticity and mode of bladder management were its associated factors; while spasticity was its predictor.

    PURPOSE: The role of diet in bladder carcinogenesis has yet to be established. To date most studies have investigated dietary components individually, rather than as dietary patterns, which may provide stronger evidence for any influence of diet on bladder carcinogenesis. The Mediterranean diet has been associated with many health benefits, but few studies have investigated its association with bladder cancer risk.

    METHODS: We investigated the potential association between the Mediterranean diet score (MDS) and risk of developing bladder cancer by pooling 13 prospective cohort studies included in the BLadder cancer Epidemiology and Nutritional Determinants (BLEND) study and applying a Cox regression analysis.

    RESULTS: Dietary data from 646,222 study participants, including 3639 incident bladder cancer cases, were analysed. We observed an inverse association between Mediterranean diet and bladder cancer risk (HRhigh 0.85 [95% CI 0.77, 0.93]). When stratifying the results on non-muscle-invasive or muscle-invasive disease or sex the association remained similar and the HR estimate was consistently below 1.00 both for medium and high adherence to the Mediterranean diet. A consistent association was observed when disregarding fat or alcohol intake.

    CONCLUSION: We found evidence that adherence to the Mediterranean diet was associated with reduced risk of developing bladder cancer, suggesting a positive effect of the diet as a whole and not just one component.

    PURPOSE: The Asian Urological Surgery Training & Education Group (AUSTEG) has been established to provide training and education to young urologists in Asia. We developed and validated a porcine bladder training model for transurethral resection of bladder tumour (TURBT).

    METHODS: Urology residents and specialists were invited to test the training model. They were asked to complete a pre-task questionnaire, to perform piecemeal and en bloc resection of 'bladder tumours' within the training model, and to complete a post-task questionnaire afterwards. Their performances were assessed by faculty members of the AUSTEG. For the face validity, a pre-task questionnaire consisting of six statements on TURBT and the training model were set. For the content validity, a post-task questionnaire consisting of 14 items on the details of the training model were set. For the construct validity, a Global Rating Scale was used to assess the participants' performances. The participants were stratified into two groups (junior surgeons and senior surgeons groups) according to their duration of urology training.

    RESULTS: For the pre-task questionnaire, a mean score of ≥ 4.0 out of 5.0 was achieved in 5 out of 6 statements. For the post-task questionnaire, a mean score of ≥ 4.5 out of 5.0 was achieved in every item. For the Global Rating Scale, the senior surgeons group had higher scores than the junior surgeons group in 8 out of 11 items as well as the total score.

    CONCLUSION: A porcine TURBT training model has been developed, and its face, content and construct validity has been established.

    OBJECTIVE: Urinary tract endometriosis involves the bladder and/or the ureters and is present in approximately 1% of women with endometriosis [1]. Bladder endometriosis is the most frequent type of urinary tract endometriosis, occurring in about 70% to 85% of cases [2,3]. Bladder endometriosis is defined as the presence of endometrial glands and stroma in the detrusor muscle. Surgically, there are 2 ways of excising this disease. The first is by transurethral bladder resection of the tumor, and the second is laparoscopic/robotic/open partial cystectomy of the bladder endometriosis. Because the nodule develops from the outer layer of the bladder wall toward the inner layer, complete excision of the endometriotic lesion is virtually unachievable with transurethral resection surgery. There is also a high risk of bladder perforation [4-8]. Partial cystectomy of the bladder runs a risk of excising normal bladder tissues because it is difficult to ascertain the margins of the bladder nodule. However, we found the best method to deal with bladder endometriosis is a combined approach whereby the margins of the bladder nodule are cut via a cystoscopy and then excision of the bladder nodule is done laparoscopically. This particular technique is presented here with an accompanying video.

    DESIGN: Excision of bladder endometriosis by first delineating the tumor via cystoscopy and simultaneously excising the nodule laparoscopically SETTING: Mahkota Medical Centre, Melaka, Malaysia.

    INTERVENTION: Here we describe a simultaneous cystoscopic and laparoscopic excision of bladder endometriosis. The patient was first seen in 2005 at age 19 years with an endometrioma. She was single (virgo intacta) at that time. She underwent a laparoscopic cystectomy. Postoperatively, she received 3 doses of monthly gonadotropin-releasing hormone (GnRH) analogue injection. She was last seen in 2006 and was well. She conceived spontaneously after that and delivered 2 babies spontaneously in 2007 and 2010 in another city. She consulted me again in April 2016 complaining of dysuria, dysmenorrhea, and inability to hold her urine. She had consulted a urologist 6 months earlier. Cystoscopy performed by the urologist showed bladder endometriosis. No further surgery was performed, and she was given GnRH analogues for 6 months. However, her symptoms persisted after completion of the GnRH analogue. Examination and ultrasound showed a large bladder nodule measuring 4.17 × 2.80 cm. Intravenous urogram showed stricture in the upper right ureter. She underwent a combined urology and gynecology surgery to excise the bladder nodule. Informed consent was obtained from the patient, and the local institutional board provided the approval. The surgery was performed with the patient in the dorsosacral position. A Verres needle was inserted into the abdomen at the umbilicus, and carbon dioxide insufflation was performed. A 10-mm trocar was inserted in the umbilicus, and a 3-dimensional laparoscope (Aesculup-BBraun Einstein Vision; BBraun, Melsungen AG, Germany) was inserted to view the pelvis. Three 5-mm trocars were inserted, 1 on the right side and 2 on the left side of the abdomen. A RUMI (CooperSurgical, Trumbull, CT) uterine manipulator was placed into the uterine cavity. Laparoscopy showed no adhesions in the upper and mid-abdomen. The appendix and the intestines looked normal. Both the ovaries and fallopian tubes were normal. Uterine insufflation with methylene blue showed that both tubes were patent. There was dense endometriosis between the bladder and fundus of the uterus. The omentum was also adherent to the site of the endometriosis. There were endometriotic nodules on the left uterosacral ligaments and the peritoneum in the wall in the pouch of Douglas. The omentum was released, and laparoscopic adhesiolysis was performed. Both the paravesical spaces lateral to the nodule were dissected out. The bladder was released from the uterus with some difficulty. The peritoneal endometriosis in the Pouch of Douglas and the nodules in the left uterosacral ligament were excised. Cystoscopy was performed and stents were first placed in both ureters. The nodule was found to be in the central position, and the margins were about 2 cm from both the ureteral orifices. The nodule was seen protruding into the bladder containing bluish lesions. Demarcation of the bladder endometriosis was done using a resectoscope. Using a needle electrode, a deep circular incision was made around the bladder nodule and into the detrusor muscle. Cystoscopic perforation of the bladder was done and was seen laparoscopically. The bladder endometriotic nodule was completely excised laparoscopically after the demarcation line created via the cystoscopy. Stay sutures were first placed at the superior and inferior edges of the defect. The bladder was repaired continuously in 1 layer using polyglactin 3-0 sutures. The nodule was placed in a bag cut into smaller pieces and removed through the umbilical incision. At the end of the surgery a cystoscopy was perform to check the integrity of the suture. The pelvis was then washed. A bladder catheter was placed. The trocars were then removed under vision, and the rectus sheath was closed using polyglactin 1 suture. The skin incisions were closed. The operation time was 2 hours. The patient received antibiotics for 10 days. She was discharged with a catheter in place on day 3. She underwent a cystogram on day 10 of the surgery, and the bladder was found to be intact. The catheter was then removed. She was seen 6 weeks after the surgery and was well without any symptoms. The ureteric catheters were removed. Histopathology confirmed bladder endometriosis. Five months later she conceived spontaneously and delivered her third child naturally in June 2017. She was seen after her delivery and was advised to take oral contraceptive pills continuously or an intrauterine contraceptive device to prevent recurrence of the endometriosis. She took the oral contraceptive pills for 3 months and then refused any further treatment. She was last seen in February 2019 and was well without any symptoms.

    CONCLUSION: In bladder endometriosis a combined approach with the urologist can assist in safely excising deep bladder endometriosis without removal of normal bladder tissue. Stents placed in the ureter assist in avoiding injury to the ureters. Demarcating the endometriotic nodule by the urologist through the bladder and excising the bladder nodule laparoscopically is both safe and effective.

    Urothelial bladder cancer is a major cause of morbidity and mortality worldwide, causing an estimated 150 000 deaths per year. Whilst non-muscle-invasive bladder tumours can be effectively treated, with high survival rates, many tumours recur, and some will progress to muscle-invasive disease with a much poorer long-term prognosis. Thus, there is a pressing need to understand the molecular transitions occurring within the progression of bladder cancer to an invasive disease. Tumour invasion is often associated with a down-regulation of E-cadherin expression concomitant with a suppression of cell:cell junctions, and decreased levels of E-cadherin expression have been reported in higher grade urothelial bladder tumours. We find that expression of E-cadherin in a panel of bladder cancer cell lines correlated with the presence of cell:cell junctions and the level of PAK5 expression. Interestingly, exogenous PAK5 has recently been described to be associated with cell:cell junctions and we now find that endogenous PAK5 is localised to cell junctions and interacts with an E-cadherin complex. Moreover, depletion of PAK5 expression significantly reduced junctional integrity. These data suggest a role for PAK5 in maintaining junctional stability and we find that, in both our own patient samples and a commercially available dataset, PAK5mRNA levels are reduced in human bladder cancer compared with normal controls. Taken together, the present study proposes that PAK5 expression levels could be used as a novel prognostic marker for bladder cancer progression.

    INTRODUCTION AND HYPOTHESIS: Our primary objective is to determine the presence of SUI at 6-12 months after surgery. The secondary objective is to determine the objective and subjective outcomes of POP.

    METHODS: A retrospective study conducted between February 2015 and July 2016 at Chang Gung Memorial Hospital. The subjects had had symptomatic anterior or apical prolapse with stage III or IV and undergone pelvic reconstructive surgery using Uphold™ LITE. Patients completed a 3-day voiding diary, urodynamic study, real-time ultrasonography and validated quality-of-life questionnaires at baseline and 12-month follow-up. Primary outcome was the absence of USI. Secondary outcomes included the objective cure rate of POP, ≤ stage 1 at the anterior/apical vaginal wall, and the subjective cure rate, negative feedback to POPDI-6.

    RESULTS: Ninety-five women were eligible. Six were excluded because of incomplete data. The postoperative de novo USI and SUI were 22.7 and 19.7%, respectively. There was significant improvement of USI in patients who had MUS insertion (93.8%) and bladder outlet obstruction (96.7%). The objective and subjective cure rate for prolapse was 95.5 and 94.3%, respectively. POP-Q measurements pre- and postoperatively were significantly improved at all points except for Gh and Pb. There was a significant difference in the distance between the bladder neck to the distal end of the mesh during straining both at both the postoperative 3rd month and 1 year.

    CONCLUSIONS: Uphold™ mesh has a 20% incidence of de novo USI with acceptable objective and subjective cure rates at 1 year postoperatively. The de novo USI rate was high but not bothersome enough to require surgery.

    Persistent urogenital sinus (PUGS) is a rare anomaly whereby the urinary and genital tracts fail to separate during embryonic development. We report a three-year-old female child who was referred to the Sabah Women & Children Hospital, Sabah, Malaysia, in 2016 with a pelvic mass. She had been born prematurely at 36 gestational weeks via spontaneous vaginal delivery in 2013 and initially misdiagnosed with neurogenic bladder dysfunction. The external genitalia appeared normal and an initial sonogram and repeat micturating cystourethrograms did not indicate any urogenital anomalies. She therefore underwent clean intermittent catheterisation. Three years later, the diagnosis was corrected following the investigation of a persistent cystic mass posterior to the bladder. At this time, a clinical examination of the perineum showed a single opening into the introitus. Magnetic resonance imaging of the pelvis revealed gross hydrocolpos and a genitogram confirmed a diagnosis of PUGS, for which the patient underwent surgical separation of the urinary and genital tracts.

    Bilateral hydroureteronephrosis involves the dilatation of the renal pelvis, calyces and ureter; it develops secondary to urinary tract obstruction and leads to a build-up of back pressure in the urinary tract, and it may lead to impairment of renal function and ultimately culminate in renal failure. Although clinically silent in most cases, it can be diagnosed as an incidental finding during evaluation of an unrelated cause. In a minority of patients, it presents with signs and symptoms. Renal calculus is the most common cause, but there are multiple non-calculus aetiologies, and they depend on age and sex. Pelviureteric junction obstruction, benign prostatic hypertrophy, urethral stricture, neurogenic bladder, retroperitoneal mass and bladder outlet obstruction are some of the frequent causes of hydroureteronephrosis in adults. The incidence of non-calculus hydronephrosis is more common in males than in females. Ultrasonography is the most important baseline investigation in the evaluation of patients with hydronephrosis. Here, we report a rarely seen case of bilateral hydroureteronephrosis associated with a hypertrophied, trabeculated bladder in an adult male cadaver, suspected to be due to a primary bladder neck obstruction, and analyse its various other causes, clinical presentations and outcomes.

    Although intravesical instillation of Bacille-Calmette-Guerin (BCG) immunotherapy was approved many decades ago as a first line therapy for intermediate to high-risk non-muscle invasive bladder cancer, its long-term efficacy is still arguable as a proportion of up to 30-40% of patients will develop recurrence or progression of their disease. Based on currently available data on the clinical application of checkpoint inhibitors in solid tumors, the mucosa-associated lymphoid tissue seems to be a main target for anti-CTLA-4 antibodies. In this manuscript we hypothesize that the combination of anti-CTLA-4 therapy with BCG might enhance the immune activity in the bladder submucosal tissue, and subsequently, improve oncological outcomes of NMIBC.
