Preparing dissertation is a challenging process that requires considerable effort and time. At the end of this process, it is necessary to publish the dissertation in order to have it reach more people and to contribute to the literature. Even though publication rate of dissertations written in urology at university hospitals in Turkey was at acceptable level, there have still been problems required to solve.

Vesico-ureteral reflux (VUR) is presented in approximately %1 of children and is associated with an increased risk of pyelonephritis and renal scarring. Despite its prevalence and morbidity, many aspects of VUR diagnosis and treatment are controversial. We objectively assessed the published data; the data base for many current diagnoses and treatment patterns of VUR is limited. Recent studies have focused on developed determination of VUR-related renal morbidity, improved stratification tools that children would benefit most from which VUR treatment option, and improved reporting of the long-term outcomes of VUR treatments in children who are at risk for VUR. In this review, the advances in the diagnosis and treatment of VUR will be accompanied by the current guidelines.

Objectives:To evaluate the long-term surgical, functional, and quality-of-life (QoL) outcomes after Holmium laser enucleation of the prostate (HoLEP) in patients with symptomatic benign prostatic hyperplasia (BPH).Materials and Methods:We retrospectively reviewed recorded data on patients who underwent HoLEP between June 2002 and February 2005. Ninety-six patients were enrolled. Demographic, perioperative, and postoperative data were recorded. On follow-up, International Prostate Symptom Scores (IPSSs), prostate-specific antigen (PSA) levels, QoL scores, peak uroflowmetric data (Qmax values), and post-voiding residual urine volumes (PVR volumes), were recorded. Complications were scored using the Clavien system. Statistical significance was set at p<0.05.Results:The mean follow-up time was 41.8±34.6 months and the mean patient age 73.2±8.7 years. The mean prostate volume was 74.6±34.3mL. Significant improvements in Qmax values, QoL, and IPSSs and decreases in PSA levels and PVR volumes were noted during follow-up (all p values=0.001). The most common complication was a requirement for re-catheterisation because of urinary retention. Two patients had concomitant bladder tumours that did not invade the muscles. Eight patients (8.3%) required re-operations; three had residual adenoma, three urethral strictures, and two residual prostate tissue in the bladder. Stress incontinence occurred in one patient (1%). All complications were of Clavien Grade 3a. We noted no Clavien 3b, 4, or 5 complications during follow-up.Conclusions:HoLEP improved IPSSs, Qmax values, PVR volumes, and QoL and was associated with a low complication rate, during extended follow-up. Thus, HoLEP can be a viable option to transurethral resection of the prostate.

Erectile dysfunction (ED) is the inability to develop normal erection or an hardening problem at various extent that causes inability to maintain the erection for the sufficient time required for a complete sexual activity. It can be the result of neurologic, psychogenic, vascular, urogenital and hormonal abnormalities. It is reported that it affects 52-67% of men between 40 and 70 years old. Numerous theories and opinions are issued in the literature in order to explain the hemodynamic changea that occur during erection and detumescence. Especially the effects of chronic diseases and psychogenic factors on the pathophysiology of erectile dysfunction are common matters of discussion in recent years. In this review, we will evaluate the current developments in the literature about the etiology of erectile dysfunction.

Small cell bladder carcinoma is a rare and frequently fatal disease. It can be distinguished from classical urothelial carcinoma microscopically and immunohistochemically. Small cell bladder carcinoma has histologically similar properties with other small cell carcinomas in other organs. It has a worse prognosis when compared to urothelial bladder cancer. Multimodal treatments are recommended although there is no widely accepted consensus regarding to the treatment algorithm because of its rarity. In this review, clinical properties and diagnosis of small cell bladder carcinoma, its histopathological and immunohistochemical properties and treatment modalities are examined.

Regional dysfunction in the autonomic nervous system may be part of OAB's etiology. SSR may be a candidate test for determining early OAB, and may also be useful for predicting antimuscarinic-refractory patients.
