Introduction: Herein, we analyzed the histopathological, oncological and functional outcomes of testis-sparing surgery (TSS) in patients with distinct risk for testicular cancer.

Methods: This is a multicenter retrospective study on consecutive patients who underwent TSS. Patients were categorized in high- or low-risk testicular germ cell tumor (TGCT) according to the presence/absence of features compatible with testicular dysgenesis syndrome.

Background And Objectives: The multiple endoclip retraction technique (MERT) was developed based on our experience with suturing renal parenchyma in laparoscopic partial nephrectomy. In this study we prospectively evaluated the one-year results of cases treated by transperitoneal laparoscopic Burch with the MERT.

Methods: The patients were evaluated with stress test, one-hour pad test, and were requested to complete the International Continence Society Incontinence Questionnaire short form (ICIQ-SF) in the postoperative period.

Objective: The present study examines the effects of the coronavirus disease 2019 pandemic on radical prostatectomy performed as part of localized prostate cancer treatment in Turkey.

Material And Methods: A retrospective analysis was made of the data of 176 patients from 8 centers in Turkey who underwent radical prostatectomy due to localized prostate cancer over the 2 years spanning March 1, 2019, to February 28, 2021. Within this timeframe, March 1, 2019, to February 28, 2020, was denoted the 1-year pre-coronavirus disease 2019 period, while March 1, 2020, to February 28, 2021, was denoted the 1-year coronavirus disease 2019 period.

To investigate the effect of four different techniques used in the treatment of ureteral stones on patients' daily physical functioning (PF) and quality of life (QoL). Patients who underwent ureterorenoscopy (URS)-with or without Double-J stenting (DJS)-and extracorporeal shock wave lithotripsy (SWL) were divided into four groups: Group I: SWL ( = 29), Group II: URS ( = 43), Group III: URS +4.8F DJS ( = 39), Group IV: URS +6F DJS ( = 42), and Group V: Control ( = 30).

Background And Objectives: The search for the perfect suture is going on and has resulted in the introduction of many different suture types into the market. The purpose of this study is to investigate the holding strength (HS) of different sutures in the renal parenchyma in an experimental study on pig kidneys.

Methods: The HS that caused sliding of the suture was investigated in 5 adult porcine kidneys with 7 suture variants.

We evaluated the association between the mean platelet volume (MPV) and monocyte/lymphocyte ratio (MLR) with brucella-caused epididymo-orchitis to determine if they could be used to differentiate between brucella and non-brucella epididymo-orchitis. The charts of 88 patients with non-brucella and 14 patients with brucella epididymo-orchitis were retrospectively reviewed. Brucellosis was diagnosed by isolating Brucella spp from a blood culture or from a serum agglutination titer ≥ 1:160 along with accompanying clinical findings.

Subcutaneous emphysema is a very rare and good-natured complication after transurethral resection of prostate (TURP). It has been reported as colon perforation, diverticulitis, and bladder perforation associated complication previously. We report the first case of a wide subcutaneous emphysema due to microperforations of prostatic capsule, without a bladder perforation after TURP.

The objective of this study was to audit the costs of retrograde intrarenal surgery (RIRS) and micropercutaneous nephrolithotomy (microperc) and compare them in terms of cost-effectiveness. We performed a retrospective analysis of 63 patients who underwent microperc and 48 patients who underwent RIRS. The cases, performed between first use and first repair, were used for this initial study.

Purpose: Chronic Prostatitis/Chronic Pelvic Pain Syndrome (CP/CPPS) is a chronic pain condition and a com­mon problem in urology clinics. Although many different etiologies and mechanisms exist, the exact cause of the disease has been unknown. Central sensitization (CS) is defined as an augmentation of responsiveness of central cortical neurons to input from peripheral nociceptive structures.

Objective: To determine the effects of two different radiation doses on sperm parameters and the role of testosterone treatment on rat spermatogenesis.

Methods: The experimental animal study was conducted at Marmara University, Istanbul, Turkey, from September 2012 to January 2013. Male Sprague Dawley 4-6 months old rats weighing 300-350g were randomely divided into 5 equal groups as control, low dose irradiation, testosterone administration following low dose irradiation, high dose irradiation, and testosterone administration following high dose irradiation.

Introduction: We investigated the monopolar and bipolar energy effects on prostate and correlated the results with the type of pathology, thus determining the relationship between tissue damage and the PSA level.

Material And Methods: One hundred and twenty four patients underwent TURP and according to the energy source, 2 groups were designed as monopolar (Group 1) and bipolar energy (Group 2). Hemoglobin and free and total PSA were measured preoperatively and 6 hours postoperatively, and differences were calculated.

To compare the outcomes of flexible ureterorenoscopy (F-URS) with extracorporeal shock wave lithotripsy (ESWL) for the treatment of upper or mid calyx kidney stones of 10 to 20 mm. A total of 174 patients with radioopaque solitary upper or mid calyx stones who underwent ESWL or F-URS with holmium:YAG laser were enrolled in this study. Each group treated with ESWL and F-URS for upper or mid calyx kidney stones were retrospectively compared in terms of retreatment and stone free rates, and complications.
