External validation and comparison of current scoring systems in retrograde intrarenal surgery: Multi-institutional study with 949 patients.

Objectives: To externally validate and compare Resorlu-Unsal stone score (RUSS), modified Seoul National University Renal Stone Complexity Score(S-ReSC), Ito's nomogram, and Retrograde Intra-Renal Surgery (R.I.R.

Effect of histopathologic characteristics on pseudocapsular invasion in the case of partial nephrectomy for renal tumours.

Objective: It is aimed to define the existence of pseudocapsular structure on renal tumours, illuminate the relation between pseudocapsular invasion and Fuhrman grade histological type that are among histopathologic prognostic risk factors and determine the relation between surgical margin positivity and existence of pseudocapsular invasion. Sequential partial nephrectomy series and relevant pathological preparations were retrospectively reviewed in order to evaluate these issues.

Methods: The study includes 123 patients diagnosed with T1 renal tumour and treated with partial nephrectomy in between January 2007 and June 2016.

Do the etiological factors in artificial urinary sphincter reimplantation cases affect success and complications?

Background/aim: The artificial urinary sphincter (AUS) is still one of the best options for incontinence treatment. It may also have an advantage for revision or reimplantation in the management of complications. In this study we aimed to discuss the etiological factors for AUS reimplantation and effects of these etiological factors on success rates, patient satisfaction rates, time to reimplantation surgery, and complications

Materials And Methods: Data from 30 patients for whom AUS reimplantation was performed were analyzed retrospectively.

Does Tadalafil Increase The Uptake of Finasteride into Prostate Tissue? A Biochemical and Histological Evaluation in Rats.

Purpose: To histopathologically and biochemically evaluate the hypothesis that tadalafil increases the uptake of a second medication into the prostate tissue by increasing the blood supply in the prostate.

Methods: Forty 12-week-old Sprague Dawley male rats were equally divided into 5 groups and were administered drugs orally as follows: Group 1 - no drugs, Group 2 - 10 days of finasteride, Group 3 - 10 days of finasteride + tadalafil, Group 4 - 30 days of finasteride, and Group 5 - 30 days of finasteride + tadalafil. At the end of 10 days of drug administration in Group1, 2, and 3, and at the end of 30 days of drug administration in Group 4 and 5,blood samples were collected from rats and analyzed for serum androgen levels.

Posttraumatic High-Flow Nonischemic Priapism.

Priapism is an uncommon disorder, and nonischemic priapism is seen less frequently in children, generally after trauma. Although it seems to be an advantage that urgent intervention is not required because of no cavernous ischemia, it is likely to be misdiagnosed because of the asymptomatic potential. We aimed to present a case of posttraumatic nonischemic priapism.

Comparison of Retrograde Intrarenal Surgery and Percutaneous Nephrolithotomy Methods in Treatment of Upper Calyceal Stones of 10-20 mm.

Objective: To compare the success and complication rates and advantages and disadvantages of retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) methods for the upper calyceal renal stones between 10 and 20 mm.

Materials And Methods: The files of 124 patients who had upper calyceal renal stones in diameter 10-20 mm were analyzed retrospectively. Sixty-one patients were randomized as Group 1 and 63 as Group 2.

Comparison of Dilation Methods in Percutaneous Nephrolithotomy: Which One Is More Successful?

Objective: Creation of the access tract is an important step in percutaneous nephrolithotomy (PNL). In this study, we compared the efficiency and safety of Amplatz, Alken, and balloon dilation methods in the creation of the access tract.

Materials And Methods: Data from 487 PNL patients admitted to 517 renal units in 3 centers were analyzed.

Comparison of Flexible Ureterorenoscopy and Laparoscopic Ureterolithotomy Methods for Proximal Ureteric Stones Greater Than 10 mm.

Objective: To examine the outcomes and to compare the effectiveness of laparoscopic ureterolithotomy and flexible URS in patients with proximal ureteral stones greater than 10 mm in diameter.

Material And Methods: A total of 150 patients who were performed laparoscopic ureterolithotomy and flexible URS because of uretral stones in our urology clinic between January 2010 and June 2015, were analyzed retrospectively. We constituted two groups; 70 patients who were performed laparoscopic ureterolithotomy were included in group I while flexible URS-performed 80 patients in group II.

Incidence of renal carcinoma in non-functioning kidney due to renal pelvic stone disease.

The objective of This study was to report our pathological findings in nephrectomy specimens from patients treated for non-functioning hydronephrotic kidney due to renal pelvic stone disease. A total of 97 patients who underwent nephrectomy for non-functioning hydronephrotic kidneys between January, 2011 and June, 2014 were retrospectively reviewed. A non-functioning kidney was defined as one having paper-thin parenchyma on urinary ultrasound or computed tomography, exhibiting no contrast visualization in the collecting duct system on intravenous urography and having a split renal function of <10% on nuclear renal function studies.

Hair coil penile tourniquet syndrome in an unusual age.

Penile tourniquet syndrome (PTS), a rare urologic emergency, may lead to undesirable results including necrosis and amputation of penis, if not diagnosed and treated appropriately. Sometimes these injuries may be accepted as a forensic case. Miscellaneous objects used for strangulation can be metallic or nonmetallic.

The effectiveness of flexible ureterorenoscopy for opaque and non-opaque renal stones.

Purpose: To evaluate the treatment success rate of flexible ureterorenoscopy (URS) for opaque and non-opaque renal stones.

Materials And Methods: Ninety-four patients, who underwent flexible URS for renal stones between October 2012 and January 2014, were included. The patients were divided into two groups according to stone radiolucency.
