Lower urinary tract function is mainly assessed by means of cystometric bladder function analysis in rodents. Conventional cystometries are usually performed as terminal analysis under urethane anesthesia. It is well known that anesthetic drugs can influence bladder function. Hence, the aim of this technique is to perform cystometric measurements of the urinary bladder and external urethral sphincter in lightly restrained awake rats. For this purpose, a bladder catheter is implanted into the bladder dome. Subsequently, two electrodes are implanted bilateral to the external urethral sphincter and a ground electrode is sutured to a non-responsive skeletal muscle...

Introduction: The optimal management strategy for urethral injuries remains controversial. Suprapubic cystostomy followed by delayed urethral reconstruction or immediate primary urethral injury repair is associated with high complication rate. Early endoscopic realignment for urethral injuries provides early definitive procedure with low complications and avoids the need for further urethral reconstruction. Materials and Methods: Between April 2007 and March 2016, 27 patients with traumatic posterior urethral disruptions were reviewed...

Introduction: Percutaneous cystostomy techniques are usually done using disposable sets in developed countries which are not affordable in poor-resource settings. However, the percutaneous technique can be done using reusable trocar or selected big size surgical blades. This is simple, safe, and cost effective in poor-resource setting. The procedure is best done under ultrasound guidance but can also be done blindly in select cases. We present our 7-year experience in ultrasound-guided percutaneous suprapubic cystostomy...

Oxidative stress is closely associated with the onset of diabetes mellitus (DM). Diabetic urethropathy is one of the most common complications of DM, but few studies have been conducted to investigate the role of oxidative stress in diabetic urethropathy. Grape seed proanthocyanidin extract (GSPE) has been previously reported to reduce oxidative injury. The present study aimed to investigate the role of oxidative stress and the protective effects of GSPE on urethral dysfunction using a streptozotocin-induced DM rat model...

Pelvic fracture with urethral injury in girls is an uncommon entity that is usually associated with concomitant vaginal lacerations. Management options vary from immediate exploration and urethral anastomosis to delayed urethroplasty. We report our experience of managing a 10-year old girl presenting 6 months after a pelvic fracture with urethrovaginal injury and a completely obliterated urethral meatus managed successfully with a single-stage bladder tube repair.

This review is based on the author's Donald Munro Lecture given at the annual conference of the Academy of Spinal Cord Injury Professionals in New Orleans, LA. Indwelling catheters play an important role in bladder management following SCI for many individuals with neurogenic bladders. There is an increased risk of UTI compared to other types of bladder management with indwelling urethral catheters but not SP catheters. To minimize the risk of symptomatic UTI, the following steps are essential: prevent bladder wall distention and resulting ischemia, maintain colonization with "good" bacteria, and prevent bladder stones...

Herein we describe a case of a 14-year-old with straddle injury to the base of the penis, sustained during an indoor rock climbing accident, who presented with severe urethrragia. Urethral injury was confirmed with retrograde urethrography. The patient became haemodynamically unstable from persistent blood loss, and corporal arterial injury was diagnosed on CT angiography. The urethraggia was successfully controlled with angioembolisation. The unique aspects of this case were the challenges in establishing the diagnosis on the background of the abnormal presentation of vascular injury of blood loss as opposed to painless priapism...

Circumcision is the most common operation with multiple complications. One of these complications is surgical such as urethrocutaneous fistula due to traumatic and ischemic injury during the operation. A 9-month infant with a history of swelling on the ventral aspect of the penile urethra during micturition was circumcised ritually in 3 months of birth and 6 months later was referred to Imam Reza Hospital with giant ventral fistula in the distal of the penis.

REVIEW
Devang Sharma, Ryan P Smith
Placement of a penile prosthesis is an excellent option for well-selected patients, offering high patient satisfaction and a low rate of complications. Most urologists who perform the procedure are not high volume implanters and may have limited experience with troubleshooting intraoperative issues. In this review, the authors use current literature to provide recommendations for the management of various intraoperative issues such as difficultly with dilation, incongruent measurement, perforation, urethral injury, crossover, complications of reservoir placement, penile curvature, glans mobility, and hemostasis are all discussed...

AIM: Renal tubular dysfunction (RTD) causing obligate production of hypoosmolar urine in boys with posterior urethral valves (PUVs) has been described. It is not known how clinically significant this is. We hypothesize that a feedback loop is present in many PUV boys who suffer deterioration of their lower urinary tract (LUT). RTD results in hypoosmolar urine, obligate polyuria, and bladder stretch-injury. The increasing back-pressure worsens RTD, thus exacerbating the injury. Coexisting renal dysplasia and acquired renal scarring exacerbate this...
