Purpose: The etiology of both adult-type ADHD and PE is not completely understood, but the studies revealing common etiologic factors for both conditions suggest a high likelihood of coexistence. We aimed to find out the prevalence of ADHD among adult males with lifetime PE.
Methods: The patients with lifetime PE were included in the study.
Purpose: Genital development is affected by pubertal process to a great extent, and puberty is a complex phenomenon that is influenced by multiple factors resulting in individual differences. We studied penile length and its relationship to pubertal stage in boys 13 to 15 years old.
Materials And Methods: Healthy boys who were candidates for military high school were evaluated between June and July 2011.
Background: The dorsal nerve block of the penis during circumcision has not been standardized and the effectiveness of the block can be changeable. The aim of this study was to determine which technique is more suitable for blocking sensory innervations of penis.
Methods: This prospective study was done on adults who voluntarily applied to be circumcised.
The objective is to compare immediate and delayed SWL as a treatment for ureter stones between 5 and 20 mm. Patients who applied to the emergency department with single, radio opaque ureteric stone of 5-20 mm size were included in the study. Patients were randomized into immediate and delayed SWL groups.

Methods: In patients with kidney stones, serum urea, creatinine, urine microalbumin, and NGAL levels were determined before SWL and at the first, second, and seventh days after SWL. In addition, patients who had undergone SWL were evaluated with Technetium-99m (Tc99m)-dimercaptosuccinic acid (DMSA) and Tc99m-diethylenetriaminepenta acetate renal scintigraphy 1 week before and 3 months after SWL.
Background And Purpose: There are no definite data indicating which modality to use to assess the efficacy of shockwave lithotripsy (SWL). Usually, plain abdominal radiography (PAR) is recommended in percutaneous nephrolithotomy (PCNL) afterward and in the follow-up of asymptomatic stones, whereas noncontrast CT (NCCT) is recommended in cases of residual fragments. We compared the efficacies of PAR and NCCT in terms of assessing the outcome of SWL treatment for radiopaque ureteral stones.

Material And Method: The charts of 86 patients who underwent surgical resection of a renal mass between 1995 and 2007 were reviewed retrospectively. Tumor size was determined both from preoperative CT and pathologic specimen.
Objectives: To examine, in a multicenter validation study designed under the guidance of the Uro-Oncology Society, the predictive accuracies of the 1998 and 2006 Kattan preoperative nomograms in Turkish patients. These 2 preoperative Kattan nomograms use preoperative parameters to estimate disease recurrence after radical prostatectomy.
Methods: A total of 1261 men with clinically localized prostate cancer undergoing radical prostatectomy were included.
Objectives: Noninvasive tests are needed for the diagnosis of chronic pelvic pain syndrome. We evaluated the significance of potassium chloride sensitivity test and urinary CTAB-precipitable uronate level in patients with chronic pelvic pain syndrome (CPPS).
Methods: We included 25 patients with interstitial cystitis (IC), and 30 patients with chronic prostatitis (CP) who applied to our outpatient clinic with the complaints of frequency, dysuria and pain on urination between the years 2003 and 2005.
The scale of parental awareness concerning children's bowel habits and its effects on voiding dysfunction were investigated. Parents of toilet-trained children older than 4 years were given questionnaires during the first interview and after follow-up of their children's bowel habits for symptoms and signs of constipation and urinary complaints. Diagnosis of constipation was made according to the Rome III criteria.

Material And Methods: A total of 43 patients with symptoms of detrusor overactivity (frequency, urgency, urge incontinence) underwent urodynamic studies (UDS). Those in whom UDS revealed phasic detrusor overactivity were evaluated using a quality of life questionnaire and voiding diaries.
Objectives: The aim of the present study was to assess and compare pre- and postoperative scrotal pain in patients with varicocele who underwent varicocelectomy with different approaches.
Methods: The study included 144 consecutive patients with left-sided varicocele who had left scrotal pain for more than 3 months. All patients underwent varicocele ligation using either a subinguinal or inguinal approach with or without external spermatic vein ligation.
Introduction: We wanted to evaluate the therapeutic effect of intravesical heparin and peripheral neuromodulation on patients with interstitial cystitis.
Materials And Methods: From March 2002 to August 2003, 8 female and 2 male subjects conform to the NIDDK criteria and not responsive to the previous conventional treatments were included in the study. Wisconsin pain scores, maximal cystometric capacities, and night and day voiding frequencies were determined and these studies were repeated in the 2nd and 12th months of the treatment with 10,000 units intravesical heparin and peripheral neuromodulation.
Introduction: Silicone has been the standard prosthesis material for the last three decades but new materials are being searched because of the known disadvantages of silicone such as migration and high cost. We wanted to test in rats whether or not polymethylmethacrylate could be an alternative to silicone.
Materials And Methods: We prepared polymethylmethacrylate and silicone testis prostheses which were similar to testis size of rats.
Objective: To evaluate changes occurring in the mucosa of the neobladder over a period of 60 months in 24 patients with orthotopic ileal neobladder.
Materials And Methods: A total of 36 male patients have undergone radical cystoprostatectomy and received an orthotopic ileal neobladder in our hospital during the last 10 years; 24 of these patients, all of whom completed a follow-up period of 60 months, are included in this study. All cases underwent a biopsy of the ileal mucosa at the time of surgery and their neobladder mucosa was then biopsied at 6, 12, 24, 36 and 60 months.
Objectives: To review the follow-up data and complications of adult patients who underwent hypospadias surgery.
Methods: The records of 88 male patients with an average age of 21.9 years (range 20 to 27) who were operated on for hypospadias from 1996 to 2001 were reviewed in two groups: primary cases and all others (at least one unsuccessful attempt to correct the hypospadias).
