OBJECTIVE:   In the perioperative period, renin-angiotensin-aldosterone system (RAAS) inhibitors may result in cardiovascular and renal functional changes. We sought to determine the acute and chronic renal functional and blood pressure effects of continuing or withdrawing angiotensin converting enzyme inhibitors (ACE-I) and angiotensin receptor blockers (ARB) after PCNL. MATERIALS AND METHODS:   This was a retrospective review of all patients undergoing PCNL at our institution from 2002-2013...

OBJECTIVE: To compare the application time and the capacity of the nomograms to predict the success of Guy's Stone Score (GSS), S.T.O.N.E. Nephrolithometry (STONE) and Clinical Research Office of the Endourological Society nephrolithometric nomogram (CROES) of percutaneous nephrolithotomy (PCNL), evaluating the most efficient one for clinical use. MATERIALS AND METHODS: We studied 48 patients who underwent PCNL by the same surgeon between 2010 and 2011. We calculated GSS, STONE and CROES based on preoperative non-contrast computed tomography (CT) images and clinical data...

INTRODUCTION: The treatment of large renal stones (≥1 cm) in paediatric patients is challenging. The usual treatment options include percutaneous nephrolithotomy (PCNL) or shockwave lithotripsy (SWL). There is a rise in the use of ureteroscopy and laser stone fragmentation (URSL) for paediatric stones; however, outcomes of treatment for large renal stones in this age group are still largely unknown. OBJECTIVE: To investigate the outcome of URSL for large paediatric renal stones ≥1 cm treated at the present institution over the last 5 years...

INTRODUCTION: With the evolution of endourologic technology, bilateral synchronous percutaneous nephrolithotomy (BS-PCNL) has emerged as a potentially practical intervention for patients with bilateral lithiasis. Although tradition has favored a staged approach, an increasing number of original studies have reported their experiences with the synchronous approach. MATERIALS AND METHODS: A Cochrane style search was performed after development of a sensitive and predefined search strategy...

In their meta-analysis, Jones and colleagues found that bilateral synchronous PCNL was associated with similar stone free outcomes and complication rates as those reported for unilateral PCNL. The authors do an excellent job in emphasizing that BS-PCNL has primarily been reported by high volume centers. Previous investigations have demonstrated that PCNL outcomes are better and complication rates are lower at high volume centers.(1) Institutions that perform few PCNLs should be cautious about performing simultaneous bilateral procedures as their complication rate may be higher and exposing the patient to acute kidney injury could prove devastating...

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 ultrasound guidance. 13 percutaneous nephrolithotomy procedures were performed in 1 stage by the urology team under ultrasound guidance...

OBJECTIVE: To report our experience of a series of PCNL from a single centre over the last 18 years in terms of patients and stone characteristics, indications, stone clearance and complications and chemical analysis of stones in a subgroup. PATIENTS AND METHODS: We retrospectively analysed the outcomes of PCNL in 3,402 adult patients who underwent the procedure between 1997 and 2014 from a prospectively maintained database. Data analysis included patients' age, sex, laboratory investigations, imaging, punctured calyx, duration of operation, volume of irrigation fluid, radiation exposure time, blood transfusion, complications and stone free status at one-month follow-up...

Urolithiasis is a significant worldwide source of morbidity, constituting a common urological disease that affects between 10 and 15% of the world population. Recent technological and surgical advances have replaced the need for open surgery with less invasive procedures. The factors which determine the indications for percutaneous nephrolithotomy include stone factors (stone size, stone composition, and stone location), patient factors (habitus and renal anomalies), and failure of other treatment modalities (ESWL and flexible ureteroscopy)...

PURPOSE: To compare outcomes and complications of percutaneous nephrolithotomy (PCNL) in the complete supine versus semi supine position in order to select the best position. MATERIALS AND METHODS: In this clinical trial, between July 2011 and May 2014, a total of 44 patients who presented for PCNL were prospectively enrolled and randomly divided into 2 groups [complete supine (n=22), andsemi supine (n = 22)]. The results in both positions were compared regarding the complexity and outcomes...

Ketamine, as a systemic and local analgesic, has been used to reduce postoperative pain in many studies. The present study was designed to assess the analgesic efficacy of nephrostomy tract infiltration of ketamine in postoperative pain after tubeless percutaneous nephrolithotomy (PCNL). Sixty-six patients with renal stone who were candidates for PCNL were randomized to two groups with 33 patients in each group. In group K, 20 mL saline solution containing 1.5 mg/kg ketamine was infiltrated into the nephrostomy tract and in group C, 20 mL saline solution was infiltrated into the nephrostomy tract at the end of surgery...

OBJECTIVES: To assess the outcomes of performing percutaneous nephrolithotomy (PCNL) in a modified supine position, more feasible for surgeons, anaesthetists, and operating theatre staff, as well as for the patient himself, and evaluating it in comparison to the standard prone position. PATIENT AND METHODS: A retrospective, case-control study was conducted between January 2011 and December 2015. In all, 197 patient's records were reviewed. The initial 101 patients were operated upon in prone position...

OBJECTIVE: To assess the safety, efficacy, and stone-free rate (SFR) of mini-percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) for the management of lower calyceal stones of ⩽2 cm, and to determine the advantages and disadvantages of each. PATIENTS AND METHODS: In all, 120 patients with lower calyceal stones of ⩽2 cm were randomly divided into two equal groups: Group A were managed by mini-PCNL and Group B by RIRS using flexible ureteroscopy and laser...

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 postoperative details were recorded. The preoperative variables analysed included: age, sex, body mass index (BMI), the presence of hypertension, diabetes mellitus, serum creatinine, degree of hydronephrosis, previous ipsilateral open renal surgery, stone size and complexity...

OBJECTIVES: To examine the safety and effectiveness of percutaneous nephrolithotomy (PCNL) as an outpatient procedure, as in most centres PCNL is performed as an inpatient procedure that necessitates postoperative hospital admission. PATIENTS AND METHODS: Our study included 186 patients undergoing PCNL for renal calculi. Only those who met strict inclusion criteria were discharged home on the same day. Preoperative eligibility criteria for outpatient management included no complex medical problem, normal renal function, and easy access to an emergency room...
