Objective: To present our experience with 454 patients who had tubeless percutaneous nephrolithotomy (TPCNL) over last 3 years.
Patients And Methods: From September 2004 to August 2007, all patients aged >14 years and undergoing PCNL were considered for TPCNL. Exclusion criteria were the presence of pyonephrosis, matrix calculi, significant bleeding or residual stone burden and need for three of more percutaneous accesses.
Objective: To define incidence of renal matrix calculi in patients undergoing percutaneous nephrolithotomy (PCNL), and describe its clinical, laboratory and radiological features; we also studied the efficacy of PCNL in managing this rare entity.
Patients And Methods: We retrospectively reviewed the records of 1368 PCNLs performed from April 2003 to March 2008, and identified 17 patients (mean age 44.3 years; 11 women and six men) having matrix calculi.
Purpose: To compare the outcome of tubeless percutaneous nephrolithotomy (PCNL) with small-bore nephrostomy drainage after PCNL.
Patients And Methods: We tested the hypothesis that tubeless PCNL is superior to small-bore nephrostomy drainage after PCNL in terms of postoperative pain, analgesic requirement, and hospital stay. To show a 10% difference in these parameters, a sample size of 30 persons per group would be needed.
Purpose: To retrospectively evaluate the safety and effectiveness of holmium laser endoscopic incision and laser lithotripsy in adults with orthotopic ureterocele and associated calculi.
Patients And Methods: From May 2003 to August 2007 at our center, 16 adults underwent transurethral incision of an ureterocele and intracorporeal holmium laser lithotripsy for associated calculi. The perioperative data of these patients were retrospectively analyzed.
Objective: To analyse the effect of prostate size on the outcome of holmium laser enucleation of prostate (HoLEP, an established procedure for treating symptomatic benign prostatic hypertrophy, BPH), in the initial 354 patients at 1 year of follow-up.
Patients And Methods: We retrospectively reviewed the records of 354 patients who had HoLEP at our institution from April 2003 to March 2007. In 235 patients the prostate weighed <60 g (group 1), in 77 it weighed 60-100 g (group 2) and in 42 >100 g (group 3).
Purpose: To present our initial experience of tubeless percutaneous nephrolithotomy (PCNL) in patients with previous ipsilateral open renal surgery.
Patients And Methods: Twenty-five patients with previous ipsilateral open renal surgery underwent tubeless PCNL at our institute. Patients with large renal and/or upper ureteral calculi, irrespective of the number and size of the stones, amount of hydronephrosis, or the renal parameters, were selected for the procedure.
Background: Splenic injury is an uncommon complication of percutaneous nephrolithotomy (PCNL).
Patients And Methods: We report herewith two cases of splenic injury that occurred during puncture of the 10th intercostal-space for PCNL.
Results And Conclusions: One of these patients presented with hypotension on day 5 after discharge from the hospital.
Objective: To evaluate, in a prospective study, the complications in 280 patients undergoing holmium laser enucleation of the prostate (HoLEP) at our institution, and to review previous reports to determine the overall incidence and types of various complications, and analyse their causes and means of prevention.
Patients And Methods: We analysed the patients' demographic, peri-operative and follow-up data, and the complications during and after surgery.
Results: HoLEP was completed successfully in 268 patients (95.
Purpose: In a prospective manner we evaluated the learning experience of an endourologist inexperienced with holmium laser prostate enucleation and its impact on surgical outcome. We also reviewed the literature to document technical features of holmium laser prostate enucleation at different institutions.
Materials And Methods: Patient demographic, perioperative and followup data were analyzed.
Purpose: To evaluate the feasibility and safety of supracostal access in tubeless percutaneous nephrolithotomy (PCNL).
Patients And Methods: From September 2004 to November 2005, tubeless PCNL using supracostal access was done for 72 patients at our institute. Patients requiring more than two percutaneous tracts or with significant intraoperative bleeding or residual stone burden were excluded from the study.
Purpose: We performed a prospective, randomized trial to assess the safety and efficacy of fibrin sealant in tubeless percutaneous nephrolithotomy.
Materials And Methods: A total of 63 patients undergoing tubeless percutaneous nephrolithotomy were randomized to receive Tisseel vapor heated sealant at the end of the procedure. Fibrin sealant was instilled under direct vision in the nephrostomy tract at the end of the procedure.
Objective: To report experience with holmium laser enucleation of the prostate (HoLEP) simultaneously with transurethral holmium laser cystolithotripsy (HLC) for managing bladder outlet obstruction (BOO) and associated vesical calculi; we also review previously reported cases of managing vesical calculi and associated BOO.
Patients And Methods: The high-powered holmium laser is a very efficient multifunctional endourological instrument that effectively fragments calculi of all compositions and is capable of haemostatic cutting of tissue, resulting in minimal bleeding after prostatic resection. A prospective study was conducted from April 2003 that included 32 men who underwent simultaneous HoLEP with transurethral HLC at our institution.
Background And Purpose: Urologic applications of laparoscopy and the holmium laser have increased exponentially in the past few years. We present our experience with sequential holmium laser enucleation of the prostate (HoLEP) and extraperitoneal laparoscopic diverticulectomy for a large symptomatic bladder diverticulum and associated bladder outlet obstruction.
Patients And Method: From June 2004 to June 2005, three patients with benign prostatic hyperplasia (BPH) and a large secondary bladder diverticulum were offered sequential HoLEP and laparoscopic extraperitoneal bladder diverticulectomy.
Purpose: In a prospective manner we studied various factors affecting fluid absorption during HoLEP. We also simultaneously evaluated changes in serum electrolytes and hemoglobin decrease during HoLEP.
Materials And Methods: This prospective study comprised of 53 patients who underwent HoLEP at our institute.
Objective: To evaluate the status of tubeless percutaneous nephrolithotomy (PCNL) in managing renal and upper ureteric calculi, from initial experience and a review of previous reports.
Patients And Methods: From September 2004 to December 2004, 46 patients were scheduled for tubeless PCNL in a prospective study. Patients with solitary kidney, or undergoing bilateral simultaneous PCNL or requiring a supracostal access were also enrolled.
Objectives: To evaluate the feasibility and safety of bilateral simultaneous tubeless percutaneous nephrolithotomy (PCNL).
Methods: From August 2004 to January 2005, 10 patients underwent bilateral simultaneous tubeless PCNL. Patients needing more than two percutaneous tracts, having significant intraoperative bleeding, or a residual stone burden were excluded from the study group.
