Introduction: Dusting, use of high frequency and low pulse energy-is commonly performed during ureteroscopic holmium laser lithotripsy but reports on the ability of this method to treat large stones via percutaneous nephrolithotomy (PCNL) are limited. We report on the first clinical feasibility of a dusting technique during PCNL using a specially designed laser suction handpiece (LSHP). Materia...

in two neighborhood calices or staghorn calculi that occupied calices without hydronephrosis and acute angle between calices were included in the study. Exclusion criteria were non-opaque calculi, long length of infundibulum, large size of residual stone, acute angle of infundibulum, and smooth surface of calculus. Forty-eight patients were enrolled in the study, including 33 men and 15 women, -

PURPOSE To evaluate the effectivity and safety of percutaneous nephrolithotomy (PCNL) in the treatment of solitary kidney with staghorn stones in prone position or in completely supine position. MATERIALS AND METHODS We retrospectively reviewed the records of 18 patients with staghorn stones in a solitary kidney treated with PCNL. 12 patients underwent PCNL in prone position (group A). 6 pati...

OBJECTIVE To present our centre's experience in the surgical treatment of lithiasis in patients with horseshoe kidney. MATERIAL AND METHODS From October 2007 to March 2011 we treated 10 patients with renal lithiasis in their horseshoe kidneys. Retrospectively, we reviewed the symptoms, medical and surgical history, the characteristics of the stones (size, location, composition) and treatments...

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...

OBJECTIVE To determine the triggers of blood transfusion in patients undergoing percutaneous nephrolithotomy (PCNL). STUDY DESIGN Observational study. PLACE AND DURATION OF STUDY The Aga Khan University Hospital, Karachi, from 1988 to 2007. METHODOLOGY The percutaneous surgery database was retrospectively reviewed to identify patients with postoperative haemorrhage and need for blood tran...

Aim: To assess the outcomes of anatrophic nephrolithotomy in terms stone clearance and change renal function. Study design: Observational study Place duration study: Department Urology Sindh Institute & Transplantation, Karachi from 1st January 2016 to 31st December 2021. Methodology: Fifty patients who underwent were enrolled. Outcomes measured clearance, pre post procedure eGFR, serum cre...

Background: Extracorporeal shockwave lithotripsy (SWL) is a procedure commonly performed to treat nephrolithiasis, with promising results in pediatric patients. However, increasing renal calculi size is directly related to worsening stone-free rates. There are few reports in the literature of >2-cm staghorn calculi that expound on the exact mechanism of treatment in the pediatric population. Ca...
