Long-term outcomes for 2-stage urethroplasty: an analysis of risk factors for urethral stricture recurrence.

PURPOSE: To report long-term results and patient reported outcomes of staged anterior urethroplasties, and isolate risk factors for recurrence. METHODS:  We reviewed urethroplasty database for all patients who underwent staged urethroplasty from 2000 to 2017. Follow-up included a cystoscopy 4 months after their 2nd stage to assess early success, and then annual follow-up thereafter with post-void residual and symptom assessment. Stricture characteristics, etiology and graft type were analyzed with regards to success. RESULTS:  Forty-nine patients were eligible for inclusion. The median stricture length was 7 cm (3-17 cm). The early success rate demonstrated by cystoscopy at 4 months was 100%. Long-term success was 96.4% in buccal graft (BMG) only patients; however, long-term success fell considerably to 53% in patients requiring any use split thickness skin graft (STSG) in the first stage. Median follow up time was 57 months (6-240 months). On analysis, age, increased stricture length and especially the use of STSG all appeared to be associated with late recurrence. The recurrence group had longer stricture length and were more likely to be panurethral. All recurrences occurred after the initial 4-month cystoscopy with a median time to recurrence of 78 months. CONCLUSION: Staged repairs that are amenable to BMG-only repairs have high long-term success rates. Increasing stricture length and the addition of split-thickness skin graft were associated with lower success rate in staged urethral reconstruction. Patients requiring staged repairs often experience recurrence in a very delayed fashion reinforcing the need for close, long-term follow up.

Complications of Genital Enlargement Surgery.

INTRODUCTION: The objective of genital enlargement surgery is to increase length and/or girth for cosmetic reasons; however, newer techniques have been recently reported to be associated with only minor complications in a small percentage of patients. AIM: We aim to report the severe complications of penile augmentation surgery seen at a referral center and describe their subsequent management. METHODS: Institutional review board approval was obtained. We reviewed our prospectively collected database for all patients who presented with complications of genital enlargement surgery from 2002-2016. MAIN OUTCOME MEASURE: Interventions following complications of genital enlargement surgery. RESULTS: 11 Patients were identified. Mean age was 47 (21-77) years. Prior procedures included subcutaneous injection of silicone outside a medical setting, girth enhancement procedures involving the subcutaneous placement or injection of substances including fat, other substances, or subcutaneous silicone implants. All patients who underwent subcutaneous penile implant underwent removal prior to presentation. Adverse changes included sexually disabling penile deformity and severe shortening, curvature, edema, subcutaneous masses, infection, non-healing wounds, and sexual dysfunction. 10 patients underwent corrective surgery, with 2 requiring multiple procedures and 3 requiring split-thickness skin grafting. All 10 patients had an improved cosmetic appearance and those who had disabling shortening had significantly improved functional length. CLINICAL IMPLICATIONS: Report of such adverse events should assist in appropriate perioperative counseling prior to genital enhancement surgery. STRENGTH & LIMITATIONS: Few reports of debilitating complications of penile enlargement exist in literature. However, without knowing the overall number of procedures performed, the true complication incidence is not known. CONCLUSION: Penile and scrotal enhancement surgery can be associated with major disabling complications, leading to deformity and functional compromise in men with prior normal anatomy and function. Patients should be aware of these risks. Furr J, Hebert K, Wisenbaugh E, et al. Complications of Genital Enlargement Surgery. J Sex Med 2018;15:1811-1817.

Massive renal size is not a contraindication to a laparoscopic approach for bilateral native nephrectomies in autosomal dominant polycystic kidney disease (ADPKD).

OBJECTIVE: To determine if massive renal size should be a contraindication for attempting a laparoscopic approach to bilateral native nephrectomies in patients with autosomal dominant polycystic kidney disease (ADPKD). PATIENTS AND METHODS: We retrospectively reviewed all laparoscopic bilateral nephrectomies performed for ADPKD at our institution from 1 January 2000 to 31 December 2012. We stratified patients by kidney weight (with or without at least one kidney weighing >2500 g) and compared perioperative data, complications, and status of kidney allografts. Additionally, the subset of patients with at least one kidney weighing >3500 g was compared with the rest of the cohort. RESULTS: We identified 68 patients; mean (range) individual kidney weight was 1984 (197-5042) g. In all, 24 patients had at least one kidney weighing >2500 g, yet patients in this group were not significantly different from the rest of the cohort for complications, estimated blood loss, transfusion rate, or duration of hospitalisation. For those who underwent simultaneous renal allotransplantation, native kidney size was not associated with graft outcomes. Additionally, of the six patients with at least one kidney weighing >3500 g, only one required a blood transfusion, and the group had no intraoperative or postoperative Clavien grade ≥3 complications. None of the cohort required conversion to open surgery. CONCLUSION: Massive size of polycystic kidneys is not a contraindication to attempting a laparoscopic approach to bilateral nephrectomies in an experienced, high-volume centre.

Postoperative changes in serum CO2 as an indicator of postoperative complications after radical cystectomy.

The purpose of this article was to review the relationship of postoperative CO2 levels to the risk of complications after radical cystectomy. In this review, we summarize the existing body of literature on the topic as well as metabolic complications after urinary diversion. Currently, there are no studies that specifically examine CO2 levels in the context of complications after radical cystectomy; therefore, we also present our own institutional data which demonstrate that a drop in postoperative CO2 levels is highly predictive of complications, the most common of which is failure to thrive. These data indicate that significant changes in CO2 levels prior to discharge after a radical cystectomy may be a harbinger of forthcoming complications.

Simultaneous kidney transplantation and bilateral native nephrectomy for polycystic kidney disease.

PURPOSE: Bilateral native nephrectomy with simultaneous kidney transplantation is becoming more common for patients with polycystic kidney disease in the living donor nephrectomy era. Single center reports evaluating the short-term and long-term outcomes of simultaneous kidney transplantation have been published but are generally limited by small sample sizes. We examined population level data to broadly define the complications of simultaneous kidney transplantation. MATERIALS AND METHODS: The Nationwide Inpatient Sample (NIS) was used to acquire data on 2,368 patients with polycystic kidney disease treated with bilateral native nephrectomy between 1998 and 2010. We performed unadjusted, multivariable and propensity score adjusted analyses of postoperative outcomes. RESULTS: A total of 2,368 patients were included in this study. The 271 patients (11.4%) who underwent simultaneous kidney transplantation had higher rates of intraoperative hemorrhage, blood transfusion and urological complications (propensity score adjusted OR 3.3, p=0.01, OR 4.2, p<0.0001 and OR 5.5, p<0.0001, respectively) but a lower in-hospital mortality rate (15.8% vs 1.1%, propensity score adjusted OR 0.10, p<0.0001). Median hospitalization was also significantly higher in patients who underwent simultaneous kidney transplantation (6 vs 9 days, p<0.0001). For the top quartile of high volume hospitals the rates of intraoperative hemorrhage, blood transfusion and urological complications remained statistically higher in patients treated with simultaneous kidney transplantation but in-hospital mortality was similar on multivariable logistic regression (OR 0.2, p=0.17). CONCLUSIONS: Except for increased rates of intraoperative hemorrhage, blood transfusion and urological complications there were no significant differences in postoperative adverse outcomes in this large, population based study of patients who underwent simultaneous kidney transplantation compared to bilateral native nephrectomy alone.

Urinary and Sexual Outcomes Following Bulbar Urethroplasty-An Analysis of 2 Common Approaches.

OBJECTIVE: To report success and patient reported urinary and sexual outcomes of patients who underwent anastomotic urethroplasty and dorsal buccal onlay urethroplasty. MATERIALS AND METHODS: Patients who underwent primary transecting anastomotic or dorsal buccal onlay urethroplasty for bulbar strictures at our institution between 1998 and 2015 were analyzed. Patients who had a prior urethroplasty, involvement of a different portion of the urethra, or a diagnosis of lichen sclerosis (LS) or hypospadias were excluded. Outcomes were assessed by cystoscopy at 4 months, validated questionnaires assessing urinary, erectile, and ejaculatory function at the time of their most recent assessment. RESULTS: A total of 40 and 139 patients were included in the dorsal buccal and anastomotic groups, respectively. Wide patency at 4-month cystoscopy was 97.5% and 100% (P= .06) and the long-term success was 95% and 99.3% (P= .06) with a mean follow-up of 51.4 and 63.3 months. Patient reported outcomes were similar with 2 exceptions: postvoid dribbling was reported more often in the onlay group (28.1% vs 8.3%, P< .0001), and tethering with erections in the anastomotic group (23.4% vs 3.1%, P= .008). Ninety-eight percent of patients in the anastomotic group and 91% in the dorsal buccal onlay group would choose their surgery again (P= .07). CONCLUSION: Both anastomotic urethroplasty and dorsal onlay graft are associated with high success with comparable satisfaction. Patient reported outcome measures were similar regardless of approach, despite inherent differences in stricture length. Our data indicates that anastomotic urethroplasty should not be avoided due to concerns of sexual side effects.

Reconstruction of Massive Localized Lymphedema of the Scrotum: Results, Complications, and Quality of Life Improvements.

OBJECTIVE: To review the surgical technique, outcomes, and complications of surgical excision of massive localized lymphedema (MLL) of the scrotum, and to determine changes in weight and quality of life (QOL) after excision. METHODS: A retrospective review was performed for all patients who have undergone excision of MLL of the scrotum at our institution between 2008 and 2014. Standard baseline characteristics, complications, pre- and postoperative weight, and QOL data were recorded. RESULTS: Eleven patients were included, with a mean follow-up of 26 months after surgery. The mean preoperative body mass index was 60, and the mean weight of resected tissue was 21 kg. No patient required an orchiectomy for completion of the resection. Skin grafting was performed in 1 patient, and the rest were closed primarily. Wound complications were common but generally managed successfully with local wound care. At the time of most recent follow-up, most patients had actually gained weight since surgery (mean weight change of +5.2 kg). However, QOL scores improved across all domains, and overall QOL improved from a mean of 1.3 preoperatively to 7.7 postoperatively (where 1 is poor, and 10 is excellent). CONCLUSION: Surgical treatment of MLL of the scrotum can be performed successfully for masses even up to 61 kg (134 lbs). Short-term wound complications are common, but subjective QOL scores improve dramatically. Despite expectations, most patients gained weight after mass removal, which indicates that they would benefit from a comprehensive weight loss plan that includes, but is not limited to, scrotal surgery.

Men with Anterior Urethral Strictures are Often Treated without Imaging or Discussion of all Treatment Options.

INTRODUCTION: We determined how men presenting to our institution with anterior urethral strictures and recurrent strictures after treatment were evaluated, counseled and treated. METHODS: A prospective study was performed of all patients presenting to our institution with recurrent anterior urethral stricture disease between 2011 and 2014. Outside records were reviewed and all patients were queried to determine if they had any urethral imaging before treatment, what treatment was given and what other options were discussed. Patients were excluded from the study if they had a history of hypospadias, or if they were initially treated more than 10 years ago or treated outside of the United States. RESULTS: A total of 100 men were included in the study, of whom 89 (89%) had prior treatment with urethral dilation or endoscopic incision. Of these patients 81 (91%) were treated without prior urethral imaging. Of the 90 patients who were treated or advised to have treatment with direct visual internal urethrotomy or dilation, 81 (90%) were not offered urethroplasty as an option. There were 66 patients who had multiple such treatments and of this group only 6 (9%) were offered urethroplasty before subsequent treatment. CONCLUSIONS: In this study the majority of men with urethral strictures were treated without urethral imaging. Furthermore, most men were not offered urethroplasty as an option before undergoing 1 or more urethral dilations or internal urethrotomies.

Bulbar urethral stricture: How to optimise the use of buccal mucosal grafts.

The use of buccal mucosa graft urethroplasty (BMGU) for bulbar urethral strictures has gained widespread popularity since the first report in 1996. Over the last two decades, there have been many modifications in the surgical technique. This, along with better understanding of urethral anatomy, has allowed the BMG to become the 'gold standard' in urethral substitution. The present article reviews the evolution and techniques of BMGU in order to answer the question - how do we optimise the use of BMGs?

Posterior Urethral Strictures.

Pelvic fracture urethral injuries are typically partial and more often complete disruptions of the most proximal bulbar and distal membranous urethra. Emergency management includes suprapubic tube placement. Subsequent primary realignment to place a urethral catheter remains a controversial topic, but what is not controversial is that when there is the development of a stricture (which is usually obliterative with a distraction defect) after suprapubic tube placement or urethral catheter removal, the standard of care is delayed urethral reconstruction with excision and primary anastomosis. This paper reviews the management of patients who suffer pelvic fracture urethral injuries and the techniques of preoperative urethral imaging and subsequent posterior urethroplasty.

The Use of Flaps and Grafts in the Treatment of Urethral Stricture Disease.

The use of various grafts and flaps plays a critical role in the successful surgical management of urethral stricture disease. A thorough comprehension of relevant anatomy and principles of tissue transfer techniques are essential to understanding the appropriate use of grafts or flaps to optimize outcomes. We briefly review these principles and discuss which technique may be best suited for a given anterior urethral stricture, depending on the location and length of the stricture, the presence or absence of an intact corpus spongiosum, and the availability of adequate and healthy penile skin.

Painful Ejaculation with Cyclobenzaprine: A Case Report and Literature Review.

INTRODUCTION: Sexual dysfunction is a well-known side effect of antidepressants. Painful ejaculation is a rare side effect that has been reported with the use of some psychiatric drugs such as triclyclic antidepressants. Cyclobenzaprine is a muscle relaxant that is structurally similar to tricyclic antidepressants. It is the most commonly prescribed muscle relaxant in the United States and accounts for 18% of all prescriptions written for chronic back pain. METHODS: A 55-year-old man was referred to our pain medicine clinic for evaluation and treatment of pain with ejaculation. MAIN OUTCOME MEASURE: The main outcome measure was to review the current published literature and case reports on painful ejaculation from medication use, in particular tricyclic antidepressants. RESULTS: After discontinuation of cyclobenzaprine, our patient's sexual dysfunction resolved. This result was consistent with the literature reviewed on the topic. CONCLUSION: Painful ejaculation is likely an underreported side effect of tricyclic antidepressants and cyclobenzaprine use. Fortunately, these symptoms are reversible and discontinuation of these medications is typically an effective cure. K raus MB , W ie CS , G orlin AW , W isenbaugh ES , and R osenfeld DM .

Dual-energy vs conventional computed tomography in determining stone composition.

OBJECTIVE: To compare the accuracy between conventional computed tomography (CT) and dual-energy CT (DECT) in predicting stone composition in a blinded, prospective fashion. METHODS: A total of 32 renal stones with known composition were scanned in vitro, first using standard CT techniques at 120 kilovolt peak (kV[p]) and then using fast-switched kilovolt DECT at 80 and 140 kilovolt peak (kV[p]). For the DECT scan, a spectral curve was created demonstrating the change of Hounsfield units (HU) across the kiloelectron volt spectrum. The composition of each stone was estimated by comparing each sample curve with curves of known materials. To attempt stone determination using single-energy CT, the HU of each stone was compared with ranges reported in previous studies. The accuracy of each method was compared. RESULTS: Included were 27 stones large enough to allow analysis. Single-energy measurements accurately identified 14 of 27 stones of all composition (52%), whereas the DECT spectral curves correctly identified 20 (74%). When analyzed by stone type, single-energy vs DECT correctly identified 12 vs 12 of the 12 uric acid stones, 2 vs 3 of the 6 struvite stones, 0 vs 3 of the 5 cystine stones, and 0 vs 2 of the 4 calcium oxalate stones, respectively. When simply attempting to differentiate uric acid vs nonuric acid stones, single-energy CT could accurately differentiate only 6 of 15 stones as nonuric acid (40%) compared with 14 of 15 stones (93%) for DECT. CONCLUSION: DECT appears to be superior to conventional CT in differentiating stone composition and is particularly accurate in differentiating nonuric acid from uric acid stones.

Proton beam therapy for localized prostate cancer 101: basics, controversies, and facts.

Proton beam therapy for prostate cancer has become a source of controversy in the urologic community, and the rapid dissemination and marketing of this technology has led to many patients inquiring about this therapy. Yet the complexity of the technology, the cost, and the conflicting messages in the literature have left many urologists ill equipped to counsel their patients regarding this option. This article reviews the basic science of the proton beam, examines the reasons for both the hype and the controversy surrounding this therapy, and, most importantly, examines the literature so that every urologist is able to comfortably discuss this option with inquiring patients.

Does prostate morphology affect outcomes after holmium laser enucleation?

OBJECTIVE: To determine whether prostate morphology or technique used has any effect on postoperative outcomes after holmium laser enucleation of the prostate. MATERIALS AND METHODS: A retrospective review of prospectively collected data was completed for all patients undergoing a holmium laser enucleation of the prostate at our institution. Prostate morphology was classified as either "bilobar" or "trilobar" according to the cystoscopic appearance. The baseline characteristics, complications, and postoperative outcomes were collected. RESULTS: A total of 304 patients with either "bilobar" (n = 142) or "trilobar" (n = 162) prostate morphology were included. The trilobar group was more likely to have longer operative times (112 vs 100 minutes, P = .04), although this difference was not significant on multivariate analysis. The postoperative outcomes were similar between the 2 groups for American Urological Association symptom score, change in American Urological Association symptom score, bother score, maximal flow rate, change in maximal flow rate, postvoid residual urine volume, and complication rate. However, the trilobar group had a significantly greater decrease in their PVR urine volume (296 vs 176 mL, P = .01), a difference that persisted on multivariate analysis. A subset analysis of the trilobar prostates revealed that performing a 2-lobe technique achieved shorter operative and enucleation times, although the difference was not significant. CONCLUSION: Those patients with trilobar prostate morphology are more likely to achieve a greater decrease in the PVR urine volume after holmium laser enucleation of the prostate. All other outcomes appeared to be similar between the 2 groups. In addition, a 2-lobe technique can be safely used for trilobar prostates when deemed feasible by the surgeon.

Metastatic malignant melanoma to the bladder: a case series.

BACKGROUND: Metastatic melanoma to the bladder is rarely reported, and the role of surgery is still largely unknown. We review 4 such cases and highlight their management and outcomes. We also review the relevant literature. METHODS: The Mayo Clinic tumor database was searched and 4 such cases were found. RESULTS: All 4 patients were treated locally with transurethral resection. The only patient who had a solitary metastasis did relatively well, having no evidence of disease 10 months after his presentation, while the other 3 died within 6 months. The literature highlights various approaches to management, but there is no definitive evidence that radical cystectomy offers any benefit over transurethral resection. CONCLUSION: Resection may improve survival in the setting of a solitary metastasis, but there is no evidence that radical cystectomy offers any benefit over local resection. With diffuse disease, however, resection is likely only beneficial for treatment of hematuria.

Anatomic site-specific disparities in survival outcomes for penile squamous cell carcinoma.

OBJECTIVE: To identify the predictors of cancer-specific mortality of penile squamous cell carcinoma (PSCC) using a population-based database. METHODS: Using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results registry, we performed a time-to-event analysis to determine which clinical parameters were useful in predicting cancer-specific mortality. RESULTS: Our cohort consisted of 2515 cases of PSCC diagnosed from 1973 to 2007. The patients were divided into 2 groups: primary tumors of the prepuce (n = 722) and primary tumors of the glans, body, and overlapping lesions of the skin (n = 1793). The median follow-up for the cohort was 39 months (range 1-411). Compared with tumors of the prepuce, tumors of the body (hazard ratio 1.61, 95% confidence interval 1.00-2.60, P = .05) and overlapping tumors of the skin (hazard ratio 1.79, 95% confidence interval 1.13-2.83, P = .01) had a greater risk of cancer-specific mortality, even when controlling for age, Surveillance, Epidemiology, and End Results stage, and tumor grade. Furthermore, the disease-specific 10-year survival rate of those with preputial tumors was 89.4% compared with 78.7% for the other 3 groups combined (P < .0001). CONCLUSION: Anatomic site-specific disparities for PSCC survival appear to exist. Patients diagnosed with PSCC of the prepuce have greater overall long-term disease-specific survival than patients with primary tumors elsewhere.

Successful management of a completely duplicated lower urinary system.

We present a young girl with an exceedingly rare case of a duplicated bladder, urethra, vulva, vagina, cervix, uterus, appendix, colon and anus, as well as a lipomyleomeningocele. This complex of anomalies has been referred to in the literature as caudal duplication syndrome. This particular case was complicated with urinary and fecal incontinence, vesicoureteral reflux, and recurrent rectovaginal fistulas. We report the successful surgical management of her condition with resulting urinary and fecal continence and resolution of reflux and fistulas.
