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.

Comparison of Success Rate in Complete Supine Versus Semi Supine Percutaneous Nephrolithotomy: (The first pilot study in randomized clinical trial).

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.

Factors affecting complications according to the modified Clavien classification in complete supine percutaneous nephrolithotomy.

Introduction: An increase in percutaneous nephrolithotomy (PCNL) has been accompanied by an increase in complications. We identified the parameters affecting the severity of complications using the modified Clavien classification (MCC).

Methods: From 2008 to 2013, 330 patients underwent complete supine PCNL using subcostal access, one-shot dilation, rigid nephroscopy, and pneumatic lithotripsy.

Transurethral intraprostatic injection of botulinum neurotoxin type A for the treatment of chronic prostatitis/chronic pelvic pain syndrome: results of a prospective pilot double-blind and randomized placebo-controlled study.

Objective: To evaluate the effect of botulinum neurotoxin type-A (BoNT-A) on chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) refractory to medical therapy.

Materials And Methods: Between November 2011 and January 2013, 60 men aged ≥18 years with CP/CPPS, and with National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores ≥10 and pain subscale scores ≥8, who were refractory to 4-6 weeks' medical therapy, underwent transurethral intraprostatic injection of BoNT-A or normal saline in a prospective pilot double-blind randomized study. The patients' NIH-CPSI total and subscale scores, American Urological Association (AUA)-symptom score (SS), visual analogue scale (VAS) and quality of life (QoL) scores and frequencies of diurnal and nocturnal urination were evaluated and compared at baseline and at 1, 3 and 6 months after injection and also were compared between the two groups.

Intra-operative stone culture as an independent predictor of systemic inflammatory response syndrome after percutaneous nephrolithotomy.

To evaluate the correlation between preoperative urine culture and stone culture findings during PCNL and choosing the appropriate antimicrobial treatment of patients with urinary tract infection or SIRS after PCNL. From April 2007 to March 2008, 51 patients aged 24-66 years underwent PCNL under general anesthesia. Statistical analysis was performed using SPSS software (v.

Bipolar transurethral vaporization: a superior procedure in benign prostatic hyperplasia: a prospective randomized comparison with bipolar TURP.

Objective: To compare the outcomes of bipolar transurethral vaporization of the prostate (TUVP) with bipolar transurethral resection of the prostate (TURP).

Materials And Methods: In a prospective randomized trial, 88 patients with moderate to severe lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH) underwent bipolar TUVP (N = 39) or bipolar TURP (N = 49) from October 2010 to November 2011. The inclusion criteria were age > 50 years, prostate volume of 30-80 mL, serum PSA < 4 ng/mL, IPSS ≥ 20, Qmax ≤ 10 mL/s and failed medical therapy.

The comparison between human leukocyte antigen system incidence in patients with bladder cancer and normal controls.

Purpose: To determine the frequency of human leukocyte antigen (HLA)-B5 in patients with bladder cancer compared with normal population.

Materials And Methods: In this cross sectional study, from November 2009 until November 2010, 35 patients with pathologic diagnosis of bladder cancer who referred to urology clinic of Razi Hospital were studied. Also, 130 healthy transplant donation volunteers who referred for HLA-typing to Guilan Blood Transfusion Organization, were selected.

Middle calyx access in complete supine percutaneous nephrolithotomy.

Background: Middle calyx access has been underused in percutaneous nephrolithotomy (PCNL), especially in the supine position. We compared the safety and efficacy outcomes between middle calyx and lower calyx accesses in the complete supine PCNL in a non-randomized single-surgeon clinical study.

Methods: Between February 2008 and October 2011, 170 patients underwent posterior subcostal single tract complete supine PCNL with one-shot dilation and middle calyx (n = 48) and lower calyx (n = 122) accesses.

Intracaval migration: an uncommon complication of ureteral Double-J stent placement.

A Double-J stent may be used for ureteral injury because of a gynecologic procedure. Intravascular migration of a Double-J stent into the inferior vena cava as an uncommon complication of ureteral stent placement is reported. Percutaneous removal of the migrated stent was performed through the left femoral vein under angiographic and fluoroscopic guidance.

Factors affecting operative time during percutaneous nephrolithotomy: our experience with the complete supine position.

Background And Purpose: Operative time influences surgical outcomes, operation-related and indirectly anesthesia-related complications. We investigated variables that affect operative time during percutaneous nephrolithotomy (PCNL) with the complete supine position.

Patients And Methods: We reviewed data of 120 patients who underwent complete supine PCNL by one surgeon.
