Comparing spinal anesthesia approaches for transurethral lithotripsy in patients with proximal ureteral stones: A randomized clinical trial of bupivacaine alone bupivacaine with fentanyl.

Despite the benefits of spinal anesthesia and the preference of anesthesiologists for this technique, it is less accepted by urologists due to the proximity of the stone place in the ureter and the possibility of pain, restlessness, and occasional movements of the patient during surgery. The current study investigated the success of bupivacaine plus intrathecal fentanyl in patients undergoing transurethral lithotripsy (TUL). In this randomized clinical trial, from April 2021 to September 2021, 54 patients with proximal urolithiasis candidates for TUL were enrolled.

Risk Factors for Intra-operative Bleeding in Percutaneous Nephrolithotomy in an Academic Center: A Retrospective Study.

Background: Percutaneous nephrolithotomy (PNL) is the treatment of choice for renal stones as a safe, effective, and minimally invasive method. However, bleeding remains a major concern in the procedure.

Objectives: This study aimed to investigate the risk factors of bleeding in PNL.

The Efficacy and Safety of On-demand Tramadol and Paroxetine Use in Treatment of Life Long Premature Ejaculation: A Randomized Double-blind Placebo-controlled Clinical Trial.

Background: Several medical therapies have been proposed for the treatment of premature ejaculation (PE). Paroxetine and tramadol were both reported to be effective in treatment of PE. In this study, the therapeutic effects of tramadol, paroxetine and placebo were compared in treatment of primary PE.

Urinary Beta-2Microglobulin: An Indicator of Renal Tubular Damage after Extracorporeal Shock Wave Lithotripsy.

Purpose: This study aims to determine extracorporeal shock wave lithotripsy (ESWL)-induced renal tubular damageand the affecting factors by measuring urinary beta2microglobulin (β2M) excretion.

Materials And Methods: This is a cross-sectional study conducted on 91 patients with renal stones who underwentESWL during 2012. Urinary beta2microglobulin was measured immediately before and after the procedure foreach patient and analyzed based on different variables to evaluate factors affecting ESWL-induced renal tubularinjury.

Application of bland-altman method in comparing transrectal and transabdominal ultrasonography for estimating prostate volume.

Background: Estimating prostate volume using less invasive transabdominal ultrasonography (TAUS) instead of transrectal ultrasonography (TRUS) is of interest in terms of identifying their agreement level. Previous reports on this subject, applied general correlation coefficient as the level of agreement. This study uses Bland-Altman method to quantify TAUS and TRUS agreement on estimating prostate volume.

Real-time scrotal ultrasound of patients with varicoceles: correlation with impaired semen analysis.

Objectives: To evaluate the potential relationship between scrotal ultrasound findings and abnormal semen analysis.

Methods: Eighty-seven patients with varicoceles underwent semen analysis and scrotal sonography. On ultrasound, estimated testes volume and the largest pampiniform vein diameters on the affected side at rest and with Valsalva manoeuvre in both the supine and upright positions were examined.

Effectiveness of tamsulosin in prevention of post-operative urinary retention: a randomized double-blind placebo-controlled study.

Purpose: Urinary retention is one of the most common complications contributing to surgical procedures. Recent studies have shown the benefits of alpha-adrenergic blockers in preventing post-operative urinary retention (POUR). The aim of this prospective study was to compare the prophylactic effect of tamsulosin with placebo on postoperative urinary retention.

Retroperitoneal ganglioneuroma mimicking right adrenal mass.

Ganglioneuroma is a rare benign tumor of the sympathetic nervous system that can arise from the adrenal medulla. Few reports have been published of the surgical resection of this rare tumor using a laparoscopic approach. We present a case of retroperitoneal ganglioneuroma that mimicked an adrenal mass on imaging and was resected laparoscopically.

Focal neuropathies following percutaneous nephrolithotomy (PCNL)--preliminary study.

Introduction: Postoperative neurological complications in pelvic and renal surgery are a well-known clinical problem and their morbidities are important. We designed this study to determine prevalence and risk factors of such complications after percutaneous nephrolithotomy (PCNL) surgery.

Material And Methods: A cross-sectional study was performed during February and July 2011 on 68 PCNL cases.

Laparoscopic transperitoneal ureterolithotomy: a single-center experience.

Introduction: This study aimed to evaluate success and complications of laparoscopic transperitoneal ureterolithotomy at our center.

Patients And Methods: From November 2008 until September 2011, 33 patients, including 22 men and 11 women, with a mean age of 45.3 years (range, 19-67 years), underwent laparoscopic ureterolithotomy at our center.

Clipless laparoscopic retroperitoneal lymph node dissection using bipolar electrocoagulation for sealing lymphatic vessels: initial series.

Purpose: To evaluate the outcome of laparoscopic retroperitoneal lymph node dissection (LRPLND) using bipolar electrocoagulation instead of clipping the lymphatic vessels.

Materials And Methods: Between August 2002 and April 2008, a total of 13 patients underwent transperitoneal LPRLND for nonseminomatous germ cell tumor of the testis. In this experience, in contrast to other techniques, we did not use clips for ligation of the lymphatic vessels; instead, we used bipolar cautery for coagulation of the lymphatic vessels.

Kidney displacement in complete supine PCNL is lower than prone PCNL.

To compare the amount of the kidney displacement in the complete supine percutaneous nephrolithotripsy (PCNL) to the prone PCNL during getting renal access. Thirty-three patients were randomly divided into two groups. The patients in group A were placed in the complete supine position and the patients in group B in the prone position.

X-ray-free percutaneous nephrolithotomy in supine position with ultrasound guidance.

Purpose: Supine percutaneous nephrolithotomy (PCNL) has numerous benefits compared to the prone position, including lower anesthesia risk, shorter operating time, and better ergonomic position for the surgeon. It is also comparable to prone position regarding vascular and bowel injuries. This study was conducted to add some more benefits by omitting X-ray in PCNL in a supine position.

Totally ultrasonography-guided percutaneous nephrolithotomy in the flank position.

Purpose: To present totally ultrasonography-guided percutaneous nephrolithotomy (PCNL) in the flank position, its preliminary results, and the practical considerations.
