Renal cell carcinoma (RCC) has been shown to cause venous migration in the inferior vena cava (IVC). It is very important for preoperative imaging to be carried out, which will decide the surgical approach for the patient. Duplication of IVC is an uncommon anomaly. We report a case of RCC with duplication of IVC.

Fulltext Retroperitoneal malignant fibrous histiocytoma with renal involvement

Med J Malaysia, 1995 Jun;50(2):189-91.

PMID: 7565195

Malignant fibrous histiocytoma is a mesenchymal tumour which can involve the genitourinary organs primarily or by secondary extension. Both conditions are rare. We report four cases of retroperitoneal malignant fibrous histiocytoma involving the kidney by local extension. Diagnosis was difficult because of diverse, non-specific clinical features and may only be reached at operation or post mortem. Prognosis is poor. Although en bloc tumour resection with nephrectomy was possible in two patients, they returned with recurrences.

Fulltext Cardiovascular Risk Reduction After Renal Denervation According to Time in Therapeutic Systolic Blood Pressure Range

Mahfoud F, Mancia G, Schmieder RE, Ruilope L, Narkiewicz K, Schlaich M, et al.

J Am Coll Cardiol, 2022 Nov 15;80(20):1871-1880.

BACKGROUND: Renal denervation (RDN) has been shown to lower blood pressure (BP), but its effects on cardiovascular events have only been preliminarily evaluated. Time in therapeutic range (TTR) of BP is associated with cardiovascular events.

OBJECTIVES: This study sought to assess the impact of catheter-based RDN on TTR and its association with cardiovascular outcomes in the GSR (Global SYMPLICITY Registry).

METHODS: Patients with uncontrolled hypertension were enrolled and treated with radiofrequency RDN. Office and ambulatory systolic blood pressure (OSBP and ASBP) were measured at 3, 6, 12, 24, and 36 months postprocedure and used to derive TTR. TTR through 6 months was assessed as a predictor of cardiovascular events from 6 to 36 months using a Cox proportional hazard regression model.

RESULTS: As of March 1, 2022, 3,077 patients were enrolled: 42.2% were female; mean age was 60.5 ± 12.2 years; baseline OSBP was 165.6 ± 24.8 mm Hg; and baseline ASBP was 154.3 ± 18.7 mm Hg. Patients were prescribed 4.9 ± 1.7 antihypertensive medications at baseline and 4.8 ± 1.9 at 36 months. At 36 months, mean changes were -16.7 ± 28.4 and -9.0 ± 20.2 mm Hg for OSBP and ASBP, respectively. TTR through 6 months was 30.6%. A 10% increase in TTR after RDN through 6 months was associated with significant risk reductions from 6 to 36 months of 15% for major adverse cardiovascular events (P < 0.001), 11% cardiovascular death (P = 0.010), 15% myocardial infarction (P = 0.023), and 23% stroke (P < 0.001).

CONCLUSIONS: There were sustained BP reductions and higher TTR through 36 months after RDN. A 10% increase in TTR through 6 months was associated with significant risk reductions in major cardiovascular events from 6 to 36 months. (Global SYMPLICITY Registry [GSR] DEFINE; NCT01534299).

Fulltext Retrograde intrarenal surgery for renal stones smaller than 2 cm

Ho CC, Hafidzul J, Praveen S, Goh EH, Bong JJ, Lee BC, et al.

Singapore Med J, 2010 Jun;51(6):512-5.

PMID: 20658113

Extracorporeal shock wave lithotripsy (ESWL) is accepted as the gold standard treatment for renal stones that are smaller than 2 cm. Recently, retrograde intrarenal surgery (RIRS) has been introduced as another form of treatment. We report our experience in dealing with renal stones smaller than 2 cm using RIRS as the primary treatment and following failed ESWL.

Fulltext Estimating glomerular filtration rate in adult kidney transplant recipients in the Asian population

Kamaruzaman L, Mohd R, Zaki FM, Hod R, Aziz AA

Saudi J Kidney Dis Transpl, 2019 6 30;30(3):587-596.

Estimation of glomerular filtration rate (GFR) in renal transplant patients is often assessed by application of creatinine-based equations. The aim was to correlate the estimated GFR (eGFR) using creatinine-based equations [Cockroft-Gault, Modification of Diet in Renal Disease (MDRD), Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI), Nankivell] with gold standard 51Cr-EDTA in kidney transplant patients in the Asian population. This is a single-center, cross-sectional study involving adult renal transplant patients. Background demographic data, medications, office blood pressure, and baseline investigations were taken. Correlations between measured GFR and eGFR were analyzed and Pearson's correlation coefficients, bias, and accuracy were assessed. Thirty-seven renal transplant patients with a mean age of 46 ± 13 years were recruited. Majority were Chinese (68%), Malay (24%), and Indian (8%). The median duration of the transplant was 84 (interquartile range 60,132) months. The mean measured GFR was 71 ± 21 mL/min/1.73 m2. Cockroft-Gault and CKD-EPI has the best correlation with 51Cr-EDTA with Pearson correlation coefficients of 0.733 (P <0.001) and 0.711 (P < 0.001), respectively. All formulae showed >80% accuracy with eGFR lies between 30% of the measured value. CKD-EPI and MDRD had the greatest accuracy with 89.2% each. Clinician may use any of these three serum creatinine-based equations to estimate GFR in kidney transplant recipients.

Fulltext Invasive aspergillosis in paediatric oncology patients

Muda Z, Ibrahim H, Abdulrahman EJ, Menon BS, Zahari Z, Zaleha AM, et al.

Med J Malaysia, 2008 Dec;63(5):415-6.

PMID: 19803305 MyJurnal

Invasive aspergillosis predominantly occurs in immunocompromised patients and is often resistant to different therapeutically strategies. However, mortality significantly increases if the central nervous system is affected. In this report we describe two cases of invasive aspergilosis, one with kidney involvement with a successful treatment while the other with pulmonary and cerebral involvement with a grave outcome.
