A 10-year-old girl presented with acute renal failure (ARF) with a serum creatinine of 7.5 mg/dL. Imaging showed bilateral hydroureteronephrosis and a large bladder stone (75×55 mm). The large bladder stone was probably the aetiology of bilateral hydronephroureter and ARF as no other cause could be found. An open cystolithotomy was performed. Ten days after the surgery, serum creatinine decreased to 0.7 mg/dL. In this report, we highlight an unusual cause of renal failure.

Background Renal colic is a common emergency department presentation. Hydronephrosis is indirect sign of urinary obstruction which may be due to obstructing ureteric calculus and can be detected easily by bedside ultrasound with minimal training. Objective To compare the accuracy of detection of hydronephrosis performed by the emergency physician with that of radiologist's in suspected renal colic cases. Method This was a prospective observational study performed over a period of 6 months. Patients >8 years with provisional diagnosis of renal colic with both the bedside ultrasound and the formal ultrasound performed were included...

PURPOSE: The percentage of parenchyma preserved plays a predominant role in predicting renal function after partial nephrectomy (PN). Currently there is no standard method to estimate preserved renal parenchyma. In this study we propose a formula of the percentage of resected and ischemic volume (PRAIV) determined by a geometric model and evaluate the relationships between renal functional change and PRAIV as well as other clinical parameters. MATERIALS AND METHODS: We identified 71 patients who underwent open PN between January 2004 and April 2014...

A 55-year-old male presented, in June 2013, with left flank pain. Investigations revealed a complete staghorn stone. He had undergone two sittings of extracorporeal shock wave lithotripsy (ESWL) in 2008 for left renal stone. One year subsequent to this, he was diagnosed with hypertension and diabetes. The management of complete staghorn stones in a single sitting is a difficult proposition. Percutaneous nephrolithotomy (PCNL) is the gold standard to manage such stones. The patient was subjected to PCNL, and complete clearance was achieved in one sitting...

Mainz pouch II is a reliable and viable technique of continent urinary diversion. Patients are at increased risk of long-term complications including urolithiasis of the upper urinary tract and reservoir. We report the case of a 67-year-old male with prior Mainz pouch II due to invasive bladder cancer treated for a large renal calculus. Percutaneous nephrolithotomy (PCNL) was successfully performed. Stone management in these type of patients is of increased interest due to existed "anatomical challenges" concerning the access and safety during the procedure...

Haemophilus species are known to colonize the upper respiratory tract and can cause infections. However Haemophilus influenzae has been rarely described as a cause of genitourinary tract infection. We report a 44-year-old nonimmunocompromised Japanese man with bacteremic pyelonephritis caused by a nontypable H. influenzae associated with a left ureteral calculus. The organism was isolated from both blood and urine cultures. Treatment consisted of 14 days of intravenous ceftriaxone and oral amoxicillin one after than other and insertion of a left ureteral stent...

A twenty-eight-year-old female with a history of suprapubic pain and recurrent urinary tract infections presents for urology referral with a kidney, ureter, and bladder radiograph showing a 4.4 cm bladder calculus and 6.5 cm distal left ureteral stone. She underwent effective cystolitholapaxy of the bladder stone. Endourologic attempt (left ureteroscopy) was unsuccessful because of ureteral stone burden. Findings at ureteroscopy revealed a duplicated system on the left with the lower pole moiety joining just proximal to the ureteral orifice...

The objective of the study is to identify factors predicting development of pyonephrosis in patients of renal calculus disease (RCD), as this knowledge is largely unknown. Patients of RCD without pyonephrosis (Group 1) or with pyonephrosis (Group 2) presenting between December 2013 and November 2015 were evaluated. All patients of RCD who had undergone either percutaneous nephrostomy (PCN) or surgical management (percutaneous nephrolithotomy/pyelolithotomy/nephrectomy) were included. Patients treated conservatively, by extracorporeal shock-wave lithotripsy and patients of bilateral RCD were excluded...

Renal Vein Thrombosis (RVT) is a rarely encountered condition. It occurs due to a hypercoagulable state in the body, caused by nephrotic syndrome and membranous nephropathy in the adults. Mode of presentation is variable. In chronic form, it may remain silent for a long time and presenting later with symptoms of pedal oedema, varicocele, proteinuria. In acute state, it manifests as flank pain, nausea or haematuria. We present a case of 25-year-old male, with left sided flank pain, haematuria and nausea for 4 days...

To assess the outcomes of percutaneous nephrolithotomy (PCNL) in bilateral staghorn calculi in pediatric patients, we have performed a retrospective analysis. Staghorn calculus is defined as stone that fills a greater part of the pelvic-caliceal system. Still, in developing countries, patients may present with staghorn calculus. PCNL is the preferred treatment modality for staghorn calculus both in adult and children. Our study included fifty-one pediatric patients (<15 years) of bilateral staghorn calculi from 2004 to 2015...

INTRODUCTION: Paraplegic patients are at greater risk of developing complications following ureteroscopic lithotripsy because of urine infection associated with neuropathic bladder, difficulties in access due to altered anatomy of urinary bladder and urethra, spinal curvature, spasticity, and contractures. We report the occurrence of large subcapsular hematoma following ureteroscopy and discuss lessons we learn from this case. CASE REPORT: A 48-year-old male patient with spina bifida underwent ureteroscopy with laser lithotripsy and ureteric stenting for left ureteric stone and staghorn calculus with hydronephrosis; laser lithotripsy was repeated after 3 months; both procedures were performed by a senior urologist and did not result in any complications...
