Nephrostomy tract dilation is one of the important steps in percutaneous renal surgery. We present our experiences with using Amplatz and metal telescopic dilators (Alken) to create a compare advantages risk factors both procedures.We retrospectively reviewed medical records 173 patients who had undergone 188 nephrolithotomy procedures between April 2007 December 2010. The nephrostomy tracts been created by (67 cases) or Alken (121 cases). Total operative time, scope formation decrease...
Purpose . To compare the effectiveness and safety of retroperitoneal laparoscopic ureterolithotomy (RLU) percutaneous antegrade ureteroscopy (PAU) in which we use semirigid treatment proximal ureteral stones. Methods Fifty-eight patients with large, impacted stones who had a history failed shock wave lithotripsy (SWL) and, retrograde ureterorenoscopy (URS) were included study between April 2007 2014. Thirty-seven PAU twenty-one RLU procedures applied. Stone-free rates, operation times,...

Objective To evaluate the effectiveness and long‐term results of using a self‐expanding metallic urethral stent (Urolume™, American Medical Systems, Minnetonka, MI, USA) to treat recurrent bulbar strictures. Patients methods Between 1990 1999, 65 stents were placed in 60 men (mean age 45.2 years, range 20–71) with stricture (mostly caused by trauma present for mean 4.3 0.16–26) who had previously undergone different unsuccessful treatments. Results During (range) follow‐up 3.8 (1–9) years...
The aim of the present study was to determine how modified Gleason grading (mGG) system affects score discrepancy between needle biopsy (NB) and radical prostatectomy (RP) investigate effect scores on nomogram predictions. When conventional (cGG) mGG systems were compared, a new obtained in NBs for 40 out 97 patients (41.2%; P < .001) RP specimens 15 (15.5%; = .005). agreement rose from 31.9% 44.3% with (P .017). However, when predictions calculated location Memorial Sloan Kettering Cancer...
Testicular spermatozoa can be retrieved successfully by the testicular sperm extraction (TESE) procedure and used for intracytoplasmic injection. Disruption in blood-testis barrier lead to production of antisperm antibodies (ASA). The aim this prospective study was investigate frequency ASA formation couples after TESE procedure.Thirty-seven were included at Urology Clinic Dr. Zekai Tahir Burak Women's Health Training Research Hospital.

Primary prostatic signet ring cell carcinoma is a rare form of cancer with poor prognosis, which generally treated traditional prostate adenocarcinoma therapy. This case report presents 70-year-old diagnosed primary carcinoma, combination radiotherapy and hormone therapy 16 month survival without an evidence the disease at follow up.
To evaluate the management of prolonged indwelling ureteral stents and newly developed KUB (kidney, ureter, bladder) grading system for classification encrusted in urolithiasis. This study involved 69 patients that had forgotten more than 6 months after urolithiasis treatment. They were categorized into 4 groups based on time reviewed retrospectively. Patients whose stent could not be removed with simple cystoscopy graded according to stone surface area system. The mean was 23.1 months....
Purpose: This study aims to evaluate the oncological and functional results of open partial nephrectomy (OPN) laparoscopic (LPN) at T1b clinical stage, which constitutes 25% renal cell carcinomas (RCC) diagnosis. Materials Methods: The characteristics 63 patients with stage solitary tumor who underwent OPN (41) or LPN (22) were compared. survival analysis was performed using Kaplan-Meier method. Univariate multivariate Cox regression analyses determine factors affecting disease-free...

Benign tumors of the proximal ureter are very rare. Many them could be confused with urothelial carcinoma and unnecessarily treated by nephrectomy. In this case, we present treatment a lymphangioma localized in upper ureter, which is an example benign tumor. During percutaneous tumor resection, organ-sparing approach, was employed.
