Predictors of graft function and survival in second kidney transplantation: A single center experience.

Background: The increasing kidney retransplantation rate has created a parallel field of research, including the risk factors and outcomes of this advanced form of renal replacement therapy. The presentation of experiences from different kidney transplantation centers may help enrich the literature on kidney retransplantation, as a specific topic in the field of kidney transplantation.

Aim: To identify the risk factors affecting primary graft function and graft survival rates after second kidney transplantation (SKT).

The safety and efficacy of ultrasound versus fluoroscopic percutaneous nephrostomy: A prospective randomized study.

Objective: The objective of this study is to compare the outcome of percutaneous nephrostomy by ultrasound (US) versus fluoroscopy including access time, volume of anesthesia required, success rate, and complications.

Methods: One hundred patients were enrolled in a prospective randomized study. Patients were divided into two groups, 50 cases each.

Mirabegron as a Medical Expulsive Therapy for 5-10 mm Distal Ureteral Stones: A Prospective, Randomized, Comparative Study.

Objective: The aim of this study was to assess the efficacy and safety of mirabegron as a medical expulsive therapy in patients with distal ureteral stones of 5-10 mm size.

Material And Methods: A prospective, comparative study included 96 patients with radiopaque distal ure- teral stones of 5-10 mm who were randomly allocated and treated by medical expulsive therapy in 2 groups from January 2019 to December 2020. Patients in group A received only ketorolac 30 mg/day for 5 days, then on demand.

Is Percutaneous Nephrolithotomy the Modality of Choice Versus Extracorporeal Shockwave Lithotripsy for a 20 to 30 mm Single Renal Pelvic Stone with ≤1000 Hounsfield Unit in Adults? A Prospective Randomized Comparative Study.

To compare the efficacy, complications, and costs of percutaneous nephrolithotomy (PNL) and extracorporeal shock wave lithotripsy (SWL) in the treatment of a 20 to 30 mm single renal pelvic stone with a density ≤1000 HU. Eighty patients were prospectively randomized to receive either PNL or SWL during May 2017 to April 2019. The relevant demographic and clinical characteristics were compared.

Efficacy of tamsulosin in medical expulsive therapy for distal ureteral calculi.

Objective: To evaluate the potential role of tamsulosin in the medical treatment of distal ureteral stones.

Material And Methods: Ninety patients with symptomatic distal ureteral calculi were enrolled. They were randomly divided into two groups: Group A (n=45) received diclofenac 100 mg on demand for 4 weeks plus levofloxacin 250 mg daily for the first week and were well hydrated; and Group B (n=45) received the same therapy plus tamsulosin 0.

Semen changes after extracorporeal shockwave lithotripsy for distal-ureteral stones.

Purpose: To determine the effects on semen of extracorporeal shockwave lithotripsy for distal-ureteral stones.

Patients And Methods: We examined the semen of 62 patients 1 day before and 1 week and 3 months after SWL for distal-ureteral stones. The results were compared with those of 62 patients similarly treated for upper- ureteral stones.

Bladder neck resection with preservation of antegrade ejaculation: Basir technique.

Purpose: To evaluate a new method of bladder neck resection and to determine if antegrade ejaculation is preserved thereafter.

Patients And Methods: Two groups of patients were treated for their bladder neck obstruction. Group A, composed of 20 patients, was treated by bladder neck resection with preservation of more than 1 cm proximal to the verumontanum.
