Vesicovaginal fistula and vesicocutaneous fistula in a patient having pelvic ectopic kidney with pyonephrosis: a unique therapeutic challenge.

BMJ Case Rep 2018 Jul 11;2018. Epub 2018 Jul 11.

Department of Urology, King George's Medical University, Lucknow, Uttar Pradesh, India.

Patients with ectopic kidney require special considerations in their management due to the anatomic characteristics predisposing the kidney to obstruction and related complications. Pelvic ectopic kidneys have the added disadvantage of being confined in the bony pelvis giving less manoeuvrability during surgery of that unit. Vesicovaginal fistulas are usually managed surgically and careful surgical dissection has to be carried out because the highest success rates are usually seen at the first operation. Read More

Division of Nephrology, Hypertension and Renal Transplantation University of Florida Gainesville Florida.

Pyonephrosis is a rare purulent infection of the upper urinary tract, which can lead to rapid clinical deterioration. While contrast-enhanced CT scan is a sensitive test, point-of-care renal sonography can serve as a quick and valuable bedside tool for diagnosis, especially when iodinated contrast use is contraindicated.

J Emerg Med 2018 07 9;55(1):e1-e4. Epub 2018 May 9.

Department of Emergency Medicine, Lewis Katz School of Medicine at Temple University, Philadelphia, Pennsylvania.

Background: Febrile urinary tract infections (UTIs) include a spectrum of pathologies from uncomplicated pyelonephritis to urosepsis, including xanthogranulomatous pyelonephritis (XGP). Most febrile UTIs are treated with antibiotics alone, but studies indicate nearly 12% of cases of presumed simple pyelonephritis require emergent urologic intervention. How to identify these individuals, while limiting unnecessary advanced imaging and delays in diagnosis, challenges all emergency providers. Read More

Can preoperative clinicoradiological parameters predict the difficulty during laparoscopic retroperitoneal simple nephrectomy? - A prospective study.

Urol Ann 2018 Apr-Jun;10(2):191-197

Department of Anesthesia, PGIMER, Dr. RML Hospital, New Delhi, India.

Introduction: Urologists tend to prefer retroperitoneal approach for open nephrectomy and transperitoneal route for laparoscopic nephrectomy. Urologists consider retroperitoneal laparoscopic approach difficult to learn and perform. There is a need to objectively define predictors of difficulty during laparoscopic retroperitoneal simple nephrectomy (LRSN) for the proper preoperative selection. Read More

Emerg Radiol 2018 Aug 13;25(4):381-386. Epub 2018 Mar 13.

Department of Diagnostic Imaging, Monash Health, Melbourne, VIC, Australia.

Purpose: To investigate if the presence of systemic inflammatory response syndrome (SIRS) in patients with urinary tract obstruction at time of presentation to the emergency department correlates with a subsequent positive urine culture and to determine if it could be used as a tool to predict the urgency of a percutaneous nephrostomy (PCN).

Department of Radiology, Section of Interventional Radiology, Memorial Sloan Kettering Cancer Center, New York, NY. Electronic address:

Urinary drainage procedures are used to treat a wide range of clinical situations including pyonephrosis, preservation of renal function in patients with ureteral obstruction, as a means to access the collecting system for stone retrieval or lithotripsy and to divert urine from a distal leak or fistula. Several different drainage devices are available and include those that provide obligatory external drainage (nephrostomy), both internal and external drainage (nephroureteral stent) and internal drainage (double-J stent). Each device requires some maintenance and effort on the patient's part-from having to undergo routine exchange of double-J stents every 3-6 months to the daily management of an external catheter and drainage bag.
