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.

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.

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.

Comparative study of hemodynamics electrolyte and metabolic changes during prone and complete supine percutaneous nephrolithotomy.

Background: Nowadays Percutaneous Nephrolithotomy (PCNL) is performed in prone and supine positions. Physiologic solutions should be used to irrigate during PCNL. Irrigation can cause hemodynamic, electrolyte and acid-base changes during PCNL.

Assessment of the efficacy of combination therapy with folic acid and tadalafil for the management of erectile dysfunction in men with type 2 diabetes mellitus.

INTRODUCTION.: Phosphodiesterase type 5 inhibitors PDE5Is are less effective in diabetic men with erectile dysfunction (ED); however, the effect of combination therapy with folic acid and PDE5Is in these patients has not been investigated. AIM.

Transurethral intraprostatic Botulinum toxin-A injection: a novel treatment for BPH refractory to current medical therapy in poor surgical candidates.

Purpose: Benign prostatic hyperplasia (BPH) is the main cause of lower urinary tract symptoms (LUTS) in elderly men. Some patients respond poorly to routine medical therapy and are not well suited for surgery, too. This study was planned to evaluate the effect of Botulinum-A on BPH refractory to current medical therapy in poor surgical candidates.

Evaluation of Tadalafil effect on lower urinary tract symptoms of benign prostatic hyperplasia in patients treated with standard medication.

Objectives: To evaluate safety and efficacy of tadalafil on lower urinary tract symptoms (LUTS) suggestive of benign prostatic hyperplasia (BPH) in patients treated with standard medication.

Materials And Methods: In this case-controlled randomized clinical trial, from November 2008 to August 2009, 132 patients with obstructive and irritative urinary tract symptoms due to BPH, IPSS ≥ 8, no indication for surgical intervention and that reached plateau levels of response to treatment were selected. These patients were randomly allocated in two groups (each containing 66 patients).

Treatment of loin pain suspected to be renal colic with papaverine hydrochloride: a prospective double-blind randomised study.

Objective: • To assess the efficacy of papaverine hydrochloride combined with a diclofenac sodium suppository to relieve renal colic compared with diclofenac suppository monotherapy, as the effect of phosphodiesterase inhibitors on ureteric muscles might reduce the pain of renal colic.

Patients And Methods: • A prospective, double-blind clinical study was performed. • In all, 550 patients aged 17-55 years with acute renal colic were randomised to two groups.

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.

Effect of terazosin on lower urinary tract symptoms and pain due to double-J stent: a double-blind placebo-controlled randomized clinical trial.

Objective: We evaluated the effect of terazosin in the improvement of lower urinary tract symptoms and flank pain in patients with internal ureteral stents.

Methods: In this double-blind randomized clinical trial, 73 patients with unilateral ureteral stone and hydroureteronephrosis who underwent insertion of an internal ureteral stent after transureteral lithotripsy (TUL) were randomized into two groups. 37 patients received terazosin 2 mg (once nightly) for 4 weeks and 36 patients received placebo for the same time duration.

Randomized controlled trial of the efficacy of isosorbide-SR addition to current treatment in medical expulsive therapy for ureteral calculi.

It has been suggested that nitrates are potent smooth muscle relaxants that may reduce pain and facilitate ureteral stone passage; therefore it may be an option for medical expulsive therapy in ureteral stones. In a prospective randomized controlled clinical trial, we evaluated the efficacy of medical expulsive therapy with isosorbide-SR 40 mg in patients with ureteral stones (≤10 mm). The patients with ureteral stones in KUB or urinary tract ultrasonography were randomized to receive methylprednisolone plus celecoxib without (control group), and with isosorbide-SR 40 mg (treatment group) for 21 days.

Is complete supine percutaneous nephrolithotripsy feasible in all patients?

Although complete supine percutaneous nephrolithotomy (csPCNL) is routine in some surgical centers throughout the world, its popularity in the field of urology due to a deficiency in its training in educational centers, as a whole, is still minimal. We evaluated the outcomes of tubeless csPCNL in this study. This study was a clinical trial, conducted by one surgical team from January 2009 to January 2010, on 117 patients in complete supine position.
