Tubeless mini-percutaneous nephrolithotomy versus retrograde intrarenal surgery for lower calyceal stones of ⩽2 cm: A prospective randomised controlled study.

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. The mean age, sex, stone size, operating time, complications, hospital stay, and SFR were compared between the groups.

Holmium Laser Enucleation of the Prostate Versus Bipolar Resection of the Prostate: A Prospective Randomized Study. "Pros and Cons".

Objective: To compare the safety, efficacy, and applicability of holmium laser enucleation of the prostate (HoLEP) and bipolar transurethral resection of the prostate (TURPb) procedures, whereas the secondary objective is to find out the advantages and disadvantages of each.

Patients And Methods: A prospective randomized study included 120 patients with benign prostatic hyperplasia that required intervention. The patients were randomized in 2 equal groups: group A managed by HoLEP and group B managed by TURPb.

Effect of multiple access tracts during percutaneous nephrolithotomy on renal function: evaluation of risk factors for renal function deterioration.

Purpose: To assess the impact of multiple access tracts during percutaneous nephrolithotomy (PCNL) on short- and midterm renal function, and to determine risk factors predicting renal function deterioration and/or recoverability.

Patients And Methods: Patients undergoing PCNL with multiple punctures were prospectively enrolled. Preoperative evaluation included dimercaptosuccinic acid and diethylenetriaminepentaacetic acid renography.

Holmium laser enucleation versus bipolar resection of the prostate: a prospective randomized study. Which to choose?

Background And Purpose: Holmium enucleation of the prostate (HoLEP) has been established as an effective therapy for patients with benign prostatic hyperplasia (BPH), with less bleeding, shorter catheterization time, and shorter hospital stay. The evolution of the bipolar transurethral resection of the prostate (TURP) raised a question: Would it be able to provide all the advantages of HoLEP and compensate for all its drawbacks, including the higher costs and the steep learning curve?

Patients And Methods: A randomized study was performed that compared HoLEP with bipolar TURP. The study included 60 patients with BPH who were randomized in two groups (1:1 fashion).

Holmium laser enucleation of the prostate: initial report of the first 230 Egyptian cases performed in a single center.

Objectives: To report our experience with the first 230 cases of holmium laser enucleation of the prostate (HoLEP) performed in a single center.

Methods: A total of 230 cases of HoLEP were performed between June 2007 and June 2008. Mean age of patients was 69.

Retrograde holmium:YAG laser disintegration of stones in pelvic ectopic kidneys: would it minimize the risk of surgery?

Purpose: To study the safety and efficacy of the holmium:YAG laser for disintegration of stones in pelvic ectopic kidneys.

Patients And Methods: Between October 2005 and October 2006 four consecutive patients with large obstructing calculi (>3 cm in diameter) in the pelves of pelvic ectopic kidneys were prepared to be treated using retrograde ureterorenoscopy and holmium:YAG laser lithotripsy. All the patients were investigated with x-rays of the kidney, ureters, and bladder (KUB) and intravenous urography (IVU).

Transurethral holmium laser enucleation of the prostate versus transurethral electrocautery resection of the prostate: a randomized prospective trial in 200 patients.

Purpose: Transurethral electrocautery resection (TURP) is generally regarded as the gold standard surgical treatment for bladder outflow obstruction due to benign prostatic hyperplasia despite its rather high morbidity. The high powered holmium:YAG laser can be used endoscopically to enucleate obstructing prostatic tissue in a relatively bloodless manner. The technique of transurethral holmium laser enucleation of the prostate (HoLEP) was compared to standard TURP for the surgical management of prostate adenomas in a randomized, prospective clinical trial.
