Acute Kidney Injury in a Previously Healthy 56-Year-Old Male Following a Direct Visual Internal Urethrotomy of a Bulbar Stricture.

Acute kidney injury (AKI) is a frequent finding in acutely ill and hospitalized patients arising from various etiologies. Anuric AKI, a more pronounced form of AKI in which less than 100 cc of urine is produced per day, is most frequently encountered in hospitalized, septic, and post-surgical patients, often secondary to shock or bilateral urinary tract obstruction. The development of anuric AKI in previously healthy patients after outpatient urological procedures presents a unique challenge to physicians, as many outpatient procedures require the routine perioperative administration of multiple nephrotoxic medications. Further complicating this clinical scenario, some surgical procedures that intrinsically involve iatrogenic injury to the kidney, ureter, bladder, or nearby organ can rarely lead to a phenomenon known as reflex anuria, an anuric state typically associated with AKI. Here, we report an unusual case of a previously healthy 56-year-old male who developed anuric AKI two days after direct visual internal urethrotomy (DVIU) for the treatment of a bulbar stricture. Non-contrast CT revealed no signs of an obstructive process, and laboratory findings supported an intrarenal cause of AKI. Consideration was given to non-steroidal anti-inflammatory drugs (NSAID)-induced nephrotoxicity, gentamicin-associated acute tubular necrosis, and propofol infusion syndrome, in addition to their potential synergistic effects. We also explore this as the first reported case of reflex anuria occurring at the level of the bulbar urethra, as most cases have involved direct injury to the kidney or ureter. Over the course of 10 days, our patient responded well to treatment with supportive measures and dialysis, with his vomiting, electrolyte abnormalities, renal state, and anuria eventually improving.

Artificial Urinary Sphincters for Treatment of Urinary Incontinence in Elderly Males.

INTRODUCTION: We sought to examine the role of advanced age (defined as >70 years), impaired cognitive function, and decreased manual dexterity in the rates of re-operation (revision or replacement) of artificial urinary sphincters (AUS). METHODS: From 1988 to 2012, 213 men underwent virgin AUS placements. Failure was defined as a revision performed for stress incontinence and replacement/exploration performed for urethral erosion/infection or mechanical failure. Kaplan-Meier curves were constructed to compare failure rates with age and Cox proportional hazard models were used to test associations. RESULTS: Advanced age was not associated with overall failure (p = 0.48), erosion/infection failure (p = 0.65), recurrent/persistent incontinence failure (p = 0.08), or mechanical failure (p = 0.36). Controlling for age, patients with cognitive dysfunction or decreased manual dexterity showed a higher rate of overall failure (p = 0.01). CONCLUSIONS: AUS placement is an excellent option to treat stress urinary incontinence in elderly men with intact cognition and good manual dexterity. AUS placement should be performed with caution in patients with impaired cognitive function or decreased manual dexterity, and additional effort should be made to identify these conditions both before and after surgery.

Anterior Urethral Stricture Disease Negatively Impacts the Quality of Life of Family Members.

Purpose. To quantify the quality of life (QoL) distress experienced by immediate family members of patients with urethral stricture via a questionnaire given prior to definitive urethroplasty. The emotional, social, and physical effects of urethral stricture disease on the QoL of family members have not been previously described. Materials and Methods. A questionnaire was administered prospectively to an immediate family member of 51 patients undergoing anterior urethroplasty by a single surgeon (SBB). The survey was comprised of twelve questions that addressed the emotional, social, and physical consequences experienced as a result of their loved one. Results. Of the 51 surveyed family members, most were female (92.2%), lived in the same household (86.3%), and slept in the same room as the patient (70.6%). Respondents experienced sleep disturbances (56.9%) and diminished social lives (43.1%). 82.4% felt stressed by the patient's surgical treatment, and 83.9% (26/31) felt that their intimacy was negatively impacted. Conclusions. Urethral stricture disease has a significant impact on the family members of those affected. These effects may last decades and include sleep disturbance, decreased social interactions, emotional stress, and impaired sexual intimacy. Treatment of urethral stricture disease should attempt to mitigate the impact of the disease on family members as well as the patient.

Botulinum Toxin Type A Injections for the Treatment of Continent Catheterizable Ileal-colic Urinary Diversion Muscularis Overactivity.

INTRODUCTION: Continent catheterizable diversions can exhibit long-term complications such as high pressures and involuntary unit contractions within the urinary reservoir, rendering them similar to neurogenic bladders. Given the similarity of these issues to neurogenic detrusor overactivity, the use of Botox injections is a logical treatment option to explore. TECHNICAL CONSIDERATIONS: A patient with a contracted Indiana pouch continent catheterizable diversion was treated with intra-pouch Botox injections after failing maximal doses of oral anticholinergic medications. This patient underwent four consecutive percutaneous Botox pouch injections every 11-12 months under general anesthesia. Flexible cystoscope via the catch stoma was attempted first on the first two surgeries, but the scope could not reach the majority of the pouch. Thus, percutaneous access was obtained under fluoroscopic guidance, and the injections were performed through a suprapubic tube access sheath. Two hundred to four hundred units of Botox (stained with methylene blue) were visually injected in 20-40 separate injection sites. Of note, the initial dose used was 200 units and was increased to 300 units then 400 units on subsequent treatments to improve results and durability. After each round of Botox injections, the patient noted resolution of her symptoms. Postinjection urodynamic studies showed normal filling with no evidence of muscularis overactivity, even at high volumes of 600 cc. CONCLUSION: Botox injections may be an excellent long-term treatment option for contracted continent catheterizable diversions, or at least used as a temporizing measure before surgical augmentation. Further studies are needed to verify the durability, complications, and long-term outcomes of this procedure.

Testicular Leydig Cell Tumor with Metachronous Lesions: Outcomes after Metastasis Resection and Cryoablation.

Leydig cell tumors represent 3% of testicular masses and usually occur in prepubertal boys and men between 30 and 60 years of age. Leydig cell tumors are benign in children but can be malignant in 10% of adults. This case report describes a 41-year-old patient who was diagnosed with a Leydig cell tumor that originated in his right testicle that subsequently metastasized to his liver, lungs, and retroperitoneum. We discuss the patient's presentation and review the radiographic findings, surgical treatment, surgical pathology, chemotherapeutic treatment, and published literature on this rare pathology.

Testicular Interposition Flap for Repair of Perineal Urinary Fistulae: A Novel Surgical Technique.

Rectourinary fistulae and urinary-cutaneous fistulae are a rare yet devastating complication. Current options for tissue interposition include rectus, gracilis, or gluteal muscle, omentum, or intestine for use in coloanal pull-through procedures. In elderly patients, testicular interposition flaps may be an excellent tissue option to use when vitalized tissue is necessary to supplement fistula repair. Elderly patients frequently have increased spermatic cord length, potentially offering a longer flap reach than use of a muscle flap. Additionally, mobilizing one of the testicles and developing it through the external inguinal ring may be a less morbid and less costly procedure than harvesting and tunneling a muscle flap. Longer follow-up and further studies are needed to determine the outcomes of this novel technique.

Nocturia: Current Levels of Evidence and Recommendations From the International Consultation on Male Lower Urinary Tract Symptoms.

OBJECTIVE: To evaluate published evidence on nocturia in men and derive expert recommendations. METHODS: The International Consultations on Urological Diseases-Société Internationale d'Urologie convened a Consultation of experts on male lower urinary tract symptoms. The Consultation assigned standardized levels of evidence and grades of recommendation to various studies of nocturia epidemiology, pathophysiology, assessment, and treatment. RESULTS: Evidence review and consensus recommendations were made in the areas of epidemiology, pathophysiology, assessment, and treatment. CONCLUSION: The review presents a condensed summary of the International Consultations on Urological Diseases-Société Internationale d'Urologie evaluation of nocturia, which offers contemporaneous expert consensus on this topic, with an assessment algorithm emphasizing the potential contribution of systemic conditions to the symptom.

Seminoma presenting as renal mass, inferior vena caval thrombus, and regressed testicular mass.

Testicular cancer is the most common malignancy of men aged 15-40. Metastatic spread classically begins with involvement of the retroperitoneal lymph nodes, with metastases to the liver, lung, bone, and brain representing advancing disease. Treatment is based on pathologic analysis of the excised testicle and presence of elevated tumor markers. We report a case of a 34-year-old male presenting with back pain who was found to have a right renal mass with tumor extension into the inferior vena cava. Subsequent biopsy was consistent with seminoma. We review this rare case and discuss the literature regarding its diagnosis and management.

Dorsal inlay buccal mucosal graft (Asopa) urethroplasty for anterior urethral stricture.

Asopa described the inlay of a graft into Snodgrass's longitudinal urethral plate incision using a ventral sagittal urethrotomy approach in 2001. He claimed that this technique was easier to perform and led to less tissue ischemia due to no need for mobilization of the urethra. This approach has subsequently been popularized among reconstructive urologists as the dorsal inlay urethroplasty or Asopa technique. Depending on the location of the stricture, either a subcoronal circumferential incision is made for penile strictures, or a midline perineal incision is made for bulbar strictures. Other approaches for penile urethral strictures include the non-circumferential penile incisional approach and a penoscrotal approach. We generally prefer the circumferential degloving approach for penile urethral strictures. The penis is de-gloved and the urethra is split ventrally to exposure the stricture. It is then deepened to include the full thickness of the dorsal urethra. The dorsal surface is made raw and grafts are fixed on the urethral surface. Quilting sutures are placed to further anchor the graft. A Foley catheter is placed and the urethra is retubularized in two layers with special attention to the staggering of suture lines. The skin incision is then closed in layers. We have found that it is best to perform an Asopa urethroplasty when the urethral plate is ≥1 cm in width. The key to when to use the dorsal inlay technique all depends on the width of the urethral plate once the urethrotomy is performed, stricture etiology, and stricture location (penile vs. bulb).
