Introduction: Recent investigations showed that anticholinergic drugs could use for the management of storage symptoms after transurethral resection of the prostate (TURP). The use of intravesical botulinum toxin-A (BTX-A) for the management of overactive bladder is rapidly increasing. In this research, we assess the efficacy of BTX-A vs solifenacin in men suffering from bladder outlet obstruction-over active bladder (BOO-OAB) managed with TURP.

5-14% of patients underwent surgery for benign prostate hyperplasia harboring prostate cancer (PCa) focus. The best management of incidental prostate cancer (iPCa) has been debated. The decision "treatment or no treatment" should be determined by predictors which accurately foretell PCa progression after transurethral resection of the prostate (TURP).

Purpose: Currently, three methods are implicated in cases of long urethral stricture including harvesting buccal mucosa of inner cheeks, harvesting lip mucosa and finally lingual mucosal graft. This study evaluated the feasibility, safety and morbidity of our "Boomerang shape" technique used for graft retrieval from the inner cheeks to repair long urethral defect cases which are usually 12-15 cm in length and 2.5 cm in width.

The retrograde approach is a modification that makes the percutaneous cystolitholapaxy (PCCL) a more trendy method, especially in operating rooms with limited facilities. The transurethral approach for bladder calculi lithotripsy by a laser has become popular among urologists. In this study, we investigate the feasibility and safety of retrograde assisted access for PCCL in comparison with transurethral cystolithotripsy by the holmium-YAG laser (Ho: YAG).

The management of Peyronie's disease (PD) has remained a therapeutic dilemma for physicians and there is no gold standard treatment. In this paper, we decided to investigate the beneficial effect of the intralesional administration of verapamil compared with the intralesional administration of verapamil plus a low-intensity laser (LIL). Research was activated from May 2016 to May 2018 and a total of 38 men aged 18 years and older completed the investigation.

Current methods for Urethral dilatation include filiforms and followers, metal sounds, balloon dilators, catheters of increasing size, introduction of a Council catheter over a guidewire, and coaxial dilators of increasing size. These methods however are effective but expensive and use of them is limited in many third world countries. In this retrospective study, we report the feasibility, complication and long-term follow-up of the newly Nelaton based urethral dilation method following by self calibration plan as a single referral center experience.

Transurethral lithotripsy (TUL) is an appropriate treatment for ureteral stones and is usually used for stones in the middle and lower part of the ureter. Different devices such as the Holmium laser, the stone basket, and the stone cone exist to prevent any fragments from retropulsion during TUL. The present study aims to compare the advantages and disadvantages of the Holmium laser, the stone basket, and the stone cone.

Purpose: Autophagy plays a critical role in PCa development. DAXX has a potent pro-survival effect by enhancing cell growth in PCa via suppression of autophagy. Here, we depicted a network governed by DAXX and SPOP by which the autophagy pathway is suppressed through the ubiquitination and modulation of key cellular signaling pathways mediators including LAMP2 and RARRES1.
