OBJECTIVE To assess the efficacy and safety of a "mini-perc" technique of percutaneous nephrolithotomy using a 14-Fr peel-away sheath for the removal of pyelocaliceal stones, and to determine appropriate inclusion criteria. MATERIALS AND METHODS From July 1999 to June 2002, the medical records and radiographic images of 72 patients who underwent the "mini-perc" technique of percutaneous nephr...

BACKGROUND Percutaneous nephrolithotomy is a minimally invasive intervention for renal stone disease. Complications, which are rare and usually presented as case reports, are diversified as the utilization of the procedure is expanded. The procedure causes less blood loss and less morbidity when compared to open surgical procedures. Yet, there are some reports involving severe bleeding and rele...

*E-mail: [email protected] We report a rare case of an ectopically placed ureteral stent, which was acceptable and functional. obstructing 8 × 15-mm proximal right-sided ureteral calculus. There were also multiple nonobstructing renal calculi on the left side. An antegrade ureteral stent was placed to relieve his infected and obstructed right kidney. During stent placement, the interventional ra...

Objective. To determine the effects of percutaneous nephrolithotomy on renal functions by using DMSA scintigraphy while considering access counts. Material and Methods. A total of 37 patients who had undergone percutaneous nephrolithotomy were included. Preoperative DMSA scans were performed a day before the surgery, whereas postoperative scans were randomized by evaluating them before (n = 25)...

BACKGROUND Percutaneous nephrolithotomy remains the standard of care for kidney stones larger than 2cm. Therefore, setting a prognosis for complete stone resolution through this method is essential. The prognostic tools available have limited prediction. OBJECTIVES To evaluate the stone-free rate in patients undergoing percutaneous nephrolithotomy with the Clinical Research Office of the Endo...

OBJECTIVE To assess the implementation of Percutaneous Nephrolithotomy (PCNL) in renal stone management and evaluate the factors for efficacy and safety of PCNL. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY Department of Urology at Jinnah Postgraduate Medical Centre, Karachi, from January 2008 to December 2011. METHODOLOGY Patients aged above 12 years of age, irrespective of gend...

Although urolithiasis is considered as a rare entity in children, it is an important health problem in the world, especially in endemic areas. When the long lifespan expectation for children is considered, minimally invasive surgical procedures such as percutaneous nephrolithotomy (PNL) have become important recently. Despite the amount of PNL procedures that have taken place in the literature ...

This study aimed to compare the totally tubeless percutaneous nephrolithotomy and standard percutaneous nephrolithotomy techniques regarding their rates of success and complications in patients with kidney stones. Patients were randomly assigned to two groups. Forty-four patients (24 men; mean age: 50.40±2.02 years) received totally tubeless percutaneous nephrolithotomy (PCNL; no nephrostomy ca...

Objective: Percutaneous Nephrolithotomy (PCNL) is one of the most effective methods for treating renal calculi. However, complicated renal calculi cannot be completely cleared through rigid nephroscopy with a single tract, whereas PCNL using multiple tracts increases the surgical risk and prolongs the post-operative recovery time. Multi-functional ureteroscopy with active and passive flexibilit...

Nephrolithiasis accelerates the renal failure in the patients with ADPKD. In order to evaluate the role of percutaneous nephrolithotomy in management of calculus in these patients, 11 patients with autosomal dominant polycystic kidney disease and renal stones were included in the study. Two patients had bilateral renal stones. All patients were treated by percutaneous nephrolithotomy under ultr...
