PURPOSE A randomized clinical trial was designed to compare the efficacy, success rate and surgical complications of percutaneous nephrolithotomy (PCNL) and laparoscopic pyelolithotomy (LP). MATERIALS AND METHODS Sixty patients with renal pelvic stones larger than 2 cm were randomly divided into two groups of LP and PCNL. All patients were followed up to three months after surgery using renal...

Urolithiasis ranks second among urological diseases, after inflammatory processes, and first surgical interventions in hospitals. The problem of this disease treatment is a long-term rehabilitation disablement, which entails significant increase costs requires changes the tactics patients. Since its introduction until today, percutaneous nephrolithotomy (PCNL) standard for nephrolithiasis with ...

Background: Majority of urologists prefer the usual prone position for percutaneous nephrolithotomy (PCNL) but due to various disadvantages PCNL, several alternative positions are being used. Aims and Objectives: The aim study was compare surgical outcomes PCNL performed using supine with those in position. Materials Methods: This a prospective observational study. After applying inclusion crit...

INTRODUCTION Percutaneous nephrolithotomy (PCNL) can involve establishing more than one access into the urinary collecting system. The present study examined whether multiple percutaneous accesses results in a more severe reduction in renal function than that after single-percutaneous access. METHODS Adult female pigs were anesthetized, and percutaneous access to the left urinary collecting s...

PURPOSE Management of patients with complex multiple renal calculi has always remained challenging and they pose many difficulties during percutaneous nephrolithotomy (PCNL) like higher incidence of residual calculus and multiple tracts requirement. The aim of our study was to evaluate the impact of pelvicalyceal system (PCS) anatomy, stone distribution and the site of puncture on the outcome o...

Percutaneous nephrolithotomy (PCNL) is a technique commonly used to remove large or multiple kidney stones and stones in the inferior calyx, with the advantages of lower morbidity rates, decrease in post-operative pain with faster recovery. Intra-abdominal irrigation fluid extravasation which leads to abdominal hypertension is a rare complication of PCNL with little reports. Early detection of ...

We evaluated the feasibility and efficacy of intermediate-supine percutaneous nephrolithotomy (PCNL) in patients with renal calculi. Fifteen patients were included in this study. The intermediate-supine operative position was modified by using a 1-L saline bag below the ipsilateral upper flank. A nephrostomy and stone extraction were performed as usual. After completion of the stone removal, a ...

OBJECTIVES To evaluate the efficacy and safety of mini- percutaneous nephrolithotomy (PCNL) in the treatment of large impacted proximal ureteral stones. METHODS We retrospectively reviewed the outcomes of 163 patients who underwent mini-PCNL between January 2006 and August 2010. Mean age was 48.6 years and mean stone size was 18.4 mm. Hydronephrosis and/or hydroureterosis appeared in all pati...

INTRODUCTION Several therapeutic methods are used in the management of lower pole caliceal calculi. This survey has been conducted to evaluate the safety and efficacy of percutaneous nephrolithotomy in the management of lower pole calculi. MATERIALS AND METHODS Fifty-five patients, 43 males and 12 females with a mean age of 41.5 (range 11 to 75) years, who had suffered from lower pole calicea...

INTRODUCTION Hemorrhage is a major complication after percutaneous nephrolithotomy (PCNL). In the current study, we analyzed the risk factors for severe bleeding after PCNL. MATERIAL AND METHODS Medical records of 982 consecutive patients undergoing PCNL at the Department of Urology, the Third Xiangya Hospital, were reviewed. The type of stone included: solitary (n = 471), multiple (n = 192) ...
