Fam XI, Singam P, Ho CC, Sridharan R, Hod R, Bahadzor B, et al.

Urinary calculi is a familiar disease. A well-known complication of endourological treatment for impacted ureteral stones is the formation of ureteral strictures, which has been reported to occur in 14.2% to 24% of cases.

Lethal hemorrhage from a ureteric-arterial-enteric fistula diagnosed by postmortem CT angiography

Rashid SN, Bouwer H, O'Donnell C

Forensic Sci Med Pathol, 2012 Dec;8(4):430-5.

Fistula formation following pelvic surgery and radiotherapy, including ureteric-arterial fistulas (UAF), is well documented, however, ureteric-arterial-enteric fistula is extremely rare. Conventional autopsy is usually required for the definitive diagnosis of pelvic vascular fistulas although an accurate diagnosis can still be complicated and challenging. The role of post-mortem computed tomography (PMCT) as an adjunct to conventional autopsy is well documented in the literature. One of the limitations of PMCT is the diagnosis of vascular conditions. Post-mortem computed tomography angiography (PMCTA) is a recently introduced technique that can assist in detecting such pathology. We present a case of post-radiotherapy ureteric-arterial-enteric fistula presenting as massive rectal and vaginal bleeding diagnosed prior to autopsy on PMCTA. The role of PMCTA in the diagnosis of such a UAF has not previously been reported in the literature.

Fulltext Total proximal ureter substitution using buccal mucosa

Fahmy O, Schubert T, Khairul-Asri MG, Stenzl A, Gakis G

The surgical treatment of a long proximal ureteral stricture is a challenging situation for reconstructive surgeons. Despite the underlying morbidities, ileal interposition and autotransplantation are the options available to treat complex cases of long segment ureteral stricture. Buccal mucosa has shown excellent results in urethroplasty. However, its use in ureteral reconstruction is infrequent. We report on a 64-year-old female patient with multiple comorbidities and prior abdominal surgeries for Crohn's disease who underwent a successful total substitution of a long segment of the proximal ureter using buccal mucosa. Regular postoperative isotope scans showed improvement in renal function. Based on the pleasant outcome of this case and review of the literature, buccal mucosa might be a viable option with low morbidity in selected cases.

Fulltext Ureterovaginal fistula: A complication of a vaginal foreign body

Lo TS, Jaili SB, Ibrahim R, Kao CC, Uy-Patrimonio MC

Taiwan J Obstet Gynecol, 2018 Feb;57(1):150-152.
PMID: 29458888 DOI: 10.1016/j.tjog.2017.12.026

OBJECTIVE: To know the diagnostic tools and proper management of ureterovaginal fistula following neglected vaginal foreign body in order to achieve optimal outcome.
CASE REPORT: A case of ureterovaginal fistula associated with a neglected vaginal foreign body. The patient was complaining of a foul-smelling vaginal discharge and lower abdominal pain. On vaginal examination, a hard and large foreign body was found. Examination under anesthesia was performed, and an aerosol cap was removed from her vagina. The patient developed urinary incontinence after removal of the foreign body. Subsequent work-up demonstrated the presence of a right ureterovaginal fistula. The patient underwent an abdominal ureteroneocystostomy. At one year follow up, the patient had fully recovered.
CONCLUSION: Ureterovaginal fistula following neglected vaginal foreign body is a serious condition. Early diagnosis, treatment of infection and proper surgical management can improve the outcome and decrease complications.

Villoglandular papillary adenocarcinoma of cervix associated with cervical intraepithelial neoplasia: a case report and review of literature

Srilatha PS, Roy A

PMID: 18306568

Well differentiated villoglandular adenocarcinoma of uterine cervix is a rare tumour which usually occurs in young women. It is considered to be an indolent tumour with favorable prognosis and most of them were treated by conservative procedures. We report a 35 year old lady who came with complaints of 3 months amenorrhoea and an episode of spontaneous bleeding. Urine pregnancy test was negative. Physical examination revealed a cervical polyp. Histopathological findings were consistent with villoglandular papillary adenocarcinoma associated with high grade cervical intraepithelial neoplasia (CIN-3). Left parametrial and left ureteral involvement, proved by biopsy, causing left hydroureteronephrosis was detected. The patient was thus found to be in an advanced stage, stage- III b (FIGO). The patient is currently undergoing radiotherapy. A review of literature showed that only occasional cases showing disease spread have been reported, suggesting caution in the management and regular follow up of the patient.

Fulltext Pathological changes and bacteriological assessments in the urinary tract of pregnant goats experimentally infected with Brucella melitensis

Mazlina M, Khairani-Bejo S, Hazilawati H, Tiagarahan T, Shaqinah NN, Zamri-Saad M

BMC Vet Res, 2018 Jun 25;14(1):203.
PMID: 29940976 DOI: 10.1186/s12917-018-1533-x

BACKGROUND: This study was conducted to investigate the pathological changes and distribution of B. melitensis in the urinary tract of pregnant goats following acute experimental infection. Six Jamnapari crossbred does in their third trimester of pregnancy were randomly assigned into two groups; Group 1 was uninfected control and Group 2 was inoculated conjunctival with 0.1 mL of the inoculums containing 109 cfu/mL of live B. melitensis. All does were sacrificed 30 days post-inoculation before the kidney, ureter, urinary bladder, urethra and vaginal swab were collected for isolation of B. melitensis. The same tissue samples were fixed in 10% neutral buffered formalin for hematoxylin and eosin, and immunoperoxidase staining.
RESULTS: None of the goats showed clinical signs or gross lesions. The most consistent histopathology finding was the infiltration of mononuclear cells, chiefly the macrophages with few lymphocytes and occasionally neutrophils in all organs along the urinary tract of the infected goats of Group 2. Other histopathology findings included mild necrosis of the epithelial cells of the renal tubules, congestion and occasional haemorrhages in the various tissues. Kidneys showed the most severe lesions. Immunoperoxidase staining revealed the presence of B. melitensis within the infiltrating macrophages and the epithelium of renal tubules, ureter, urethra and urinary bladder. Most extensive distribution was observed in the urinary bladder. Brucella melitensis was successfully isolated at low concentration (3.4 × 103 cfu/g) in the various organs of the urinary tract and at high concentration (2.4 × 108 cfu/mL) in the vaginal swabs of all infected goats. Although B. melitensis was successfully isolated from the various organs of the urinary tract, it was not isolated from the urine samples that were collected from the urinary bladder at necropsy.
CONCLUSION: This study demonstrates the presence of low concentrations of B. melitensis in the organs of urinary tract of pregnant does, resulting in mild histopathology lesions. However, B. melitensis was not isolated from the urine that was collected from the urinary bladder.
