A 66-year-old woman had a 22 mm right kidney stone accompanied with a horseshoe kidney. The size of this stone had been increasing gradually from 7 mm to 22 mm during the past 5 years. Although apparent pelviuretic junction stenosis could not be identified by intravenous urography, external pelvis was dilated in both kidneys. Complete excretion of fragmented stones by extracorporeal shockwave l...

OBJECTIVES To evaluate factors contributing to bleeding after percutaneous nephrolithotomy (PCNL) and ways of managing this complication, as bleeding is a serious sequela that requires prompt management. PATIENTS AND METHODS The demographic and procedural data of 200 patients, who underwent unilateral PCNL during a 20-month period, were prospectively collected. Preoperative, operative, and po...

OBJECTIVES To explore the history of symptomatic cystine stone formation. Cystinuria is a genetic defect that may result in the formation of recurrent cystine calculi. METHODS Thirty-four patients with cystinuria were retrospectively evaluated for treatment patterns, medical prophylaxis, and renal outcome. Patients were offered a conservative surgical regimen and routine radiographic and labo...

PURPOSE To correlate the presence of secondary signs of non-enhanced computed tomography (NECT) in renal units harboring ureteral calculi with intraoperative findings and treatment outcome after holmium:yttrium-aluminum-garnet laser (Ho:YAG) ureterolithotripsy. SUBJECTS AND METHODS Two-hundred patients were prospectively included after ureteral calculi were detected on NECT. All patients unde...

OBJECTIVES To assess the probability of spontaneous stone passage and its predictors after drainage of obstructed kidney by JJ stent, as insertion of an internal ureteric stent is often used for renal drainage in cases of calcular ureteric obstruction. PATIENTS AND METHODS Between January 2011 and June 2013, patients for whom emergent drainage by ureteric stents were identified. The patients'...

OBJECTIVE To determine the efficacy and safety of high-power holmium: yttrium aluminum-garnet (Ho:YAG) laser lithotripsy for multitract modified minimally invasive percutaneous nephrolithotomy (MPCNL) in the treatment of patients with large staghorn renal calculi. METHODS A randomized, prospective study was conducted. Two-hundred seventy-three consecutive patients (291 renal units) with large...

Chronic renal failure is an uncommon disease in children with some difference in the etiology in different countries. In this study on 180 children (From 1987 to 1997 in Shiraz) with age range of 3 months to 15 years (mean 8.6±4.2 years). The male to female ratio was 1. 57: 1. The etiology of chronic renal failure in decreasing order of frequency were: reflux nephropathy (25 % ) , glbmerular di...

INTRODUCTION The treatment of large renal stones in children can be challenging often requiring combination therapy and multiple procedures. The purpose of this video is to describe our technique of robotic nephrolithotomy and pyelolithotomy for complex renal stone disease in children, and to demonstrate the utility of the robotic ultrasound probe to aid with stone localization. MATERIALS AND...

Background According to high prevalence of renal stone in children, we evaluated the efficacy of treatment with potassium citrate and its correlation with metabolic disorders in children less than two years of age with renal stone and microlithiasis. Methods In this cross- sectionaly study, 100 patients (less than 2 years old) with renal stone or microlitiasis were evaluated for metabolic dis...

OBJECTIVE To determine a difference in the stone-free-rate among different renal locations in children after extracorporeal shockwave lithotripsy (ESWL). STUDY DESIGN A descriptive study. PLACE AND DURATION OF STUDY Urology Department, Shifa International Hospital, Islamabad, Pakistan, from January 2007 to June 2015. METHODOLOGY The study included children who underwent ESWL, divided into...
