Clinically insignificant residual fragments (CIRFs) are described as asymptomatic, noninfectious and nonobstructive stone fragments (≤4 mm) remaining in the urinary system after the last session of any intervention (ESWL, URS or PCNL) for urinary stones. Their insignificance is questionable since CIRFs could eventually become significant, as their presence may result in recurrent stone growth a...
objectives:the aim of the present study was to assess the analgesic efficacy of iv ketamine injection inaddition to nephrostomy tract infiltration of ketamine – bupivacaine on postoperative pain relief after tubeless percutaneous nephrolithotomy (pcnl). patients and methods: patients (n = 100), with renal stone who were candidates for pcnl were randomized to five groups with 20 cases in each: g...
Objective:
 To report our experience in percutaneous nephrolithotomy and endoscopic urinary tract stone surgery patients with diversion vesicostomy.
 Materials Methods:
 Data of 21 or vesicostomy who underwent for stones clinic between January 2008 2020 were retrospectively analyzed. Eight (38%) nephrolithotomy, 2 (9.5%) antegrade flexible ureteroscopy, 4 (19.0%) retrograde semi-...
Two patients with renal pelvic stone in a horseshoe kidney who underwent a percutaneous nephrolithotripsy (PNL) are presented. Case 1 was a 36-year-old man with a 20 x 12 mm right renal pelvic stone in a horseshoe kidney. Case 2 was a 47-year-old man who had been followed up at our clinic for a horseshoe kidney and was found to have a 15 x 10 mm left renal pelvic stone. We found that percutaneo...
PURPOSE Percutaneous nephrolithotomy (PCNL) has been the preferred procedure for the removal of large renal stones in Iran since 1990. Recently, we encountered a series of devastating neurologic complications during PCNL, including paraplegia and hemiplegia. There are several reports of neurologic complications following PCNL owing to paradoxical air emboli, but there are no reports of parapleg...
INTRODUCTION The goal of percutaneous nephrolithotomy (PCNL) is to ensure complete stone clearance with minimal morbidity. The key to complete clearance is accurate technique, expertise and instrumentation. METHODS We systematically reviewed available reports that were identified using a PubMed/Medline search. The keywords used were 'PCNL' and 'advances in PCNL'. The findings were reviewed un...
Objective: In this study, we aimed to compare the success and complication rates of percutaneous nephrolithotomy (PCNL) according preoperative glomerular filtration (GFR) patients who underwent PCNLdue kidney stones. Material Methods: Between January 2012 December 2016, 794 PCNL due Stones were evaluated retrospectively. Preoperative GFR values calculated Cockcroft –Gault formula. The with valu...
Current EAU guide recommend the PCNL as the gold standard procedure for stones larger than 2 cm and stones larger than 1 cm if in the lower calyx in patients with unfavorable factors for SWL. Residual fragments are commonly seen after both, ESWL and after intracorporeal lithotripsy. The incidence of residual stones after PCNL ranges from 10% to 60%. But some of these studies with high success r...
OBJECTIVES To evaluate an alternative approach to tubeless surgery that allows a second percutaneous procedure using the same nephrostomy tract. METHODS Twenty patients underwent percutaneous nephrolithotomy from September 2012 to May 2013 at our institution. Inclusion criteria were: absence of urinary infection, single puncture and operative time less than 2 h. Following the procedure the in...
