Erectile dysfunction after anterior urethroplasty: a prospective analysis of incidence and probability of recovery--single-center experience

The urinary and sexual outcomes of buccal mucosal graft urethroplasty versus end-to-end anastomosis: a systematic review with meta-analysis

Background

The urinary and sexual outcomes after urethroplasty may be a concern for patients, but there are still some controversies regarding the consequences of buccal mucosal graft urethroplasty (BMG) in terms of erectile dysfunction (ED).

Aim

This meta-analysis aimed to compare urinary and sexual outcomes of BMG and end-to-end urethroplasty (EE).

Methods

The PubMed, Web of Science, Cochrane, and Embase databases were searched until February 31, 2023. Data extraction and quality assessment were performed by 2 designated researchers. Dichotomous data were analyzed as odds ratios with 95% confidence intervals (CIs). Heterogeneity across studies was assessed by the I2 quantification, and publication bias using Begg's and Egger's tests. Meta-analysis was performed using RevMan software.

Outcomes

Outcomes included stricture recurrence, ED, penile complications, and voiding symptoms.

Results

Eighteen studies, including 1648 participants, were included in our meta-analysis. The meta-analysis revealed that there was no significant difference in stricture recurrence (OR = 0.74; 95% CI, 0.48-1.13; P = .17) and voiding symptoms (OR = 1.12; 95% CI, 0.32-3.88; P = .86) between the BMG group and the EE group. BMG was associated with lower risk of penile complications (OR = 0.40; 95% CI, 0.24-0.69; P = .001) and ED (OR = 0.53, 95% CI, 0.32-0.90, P = .02).

Clinical Implications

The study may help clinicians choose procedures that achieve better recovery of the urological and sexual function in the treatment of urethral stricture.

Strengths and Limitations

This meta-analysis is the first to evaluate the urinary and sexual outcomes of BMG vs EE. A limitation is that most of the included studies were retrospective cohort studies.

Conclusion

BMG is as effective as EE in the treatment of bulbar urethral stricture, but BMG has fewer complications and ED than EE.

The best method for erection function in urethroplasty; is excision and primary anastomosis or buccal mucosal graft urethroplasty?

INTRODUCTION

The aim of this study is to evaluate and compare erection function (EF) after Excision and Primary Anastomosis Urethroplasty (EPAU) and Buccal Mucosal Graft Urethroplasty (BMGU) in bulbar urethral stricture.

METHODS

Patients who underwent urethroplasty were identified retrospectively. The criteria for inclusion in the study were determined as being over 18 years old and under 70 years old, being sexually active. Exclusion criteria are; preoperative severe erectile dysfunction, stricture outside the bulbar urethra, psychosocial incompatibility, urethral stricture related to pelvic fracture, follow-up time less than a year. As the primary endpoint, the International Index of Erectile Function-5 (IIEF-5) was determined as a comparison of EF in the preoperative and third, sixth and twelfth months after surgery. The secondary endpoint was the evaluation of the effects of demographic data, stricture and treatment characteristics on EF.

RESULTS

Fifty patients were identified considering the inclusion/exclusion criteria. It was observed that there were 30 patients who underwent EPAU and 20 patients who underwent BMGU. At the third month after surgery, EF showed a statistically significant decrease in the EPAU group. In both patient groups, it was observed that the early negative effects after the operation in EF started to improve in the sixth month and returned to the baseline level by the first year.

CONCLUSION

EPAU and BMGU techniques have a similar effect on EF in the medium and long term. Both methods can be used safely and effectively in the appropriate patient group.

Low risk of erectile dysfunction after nontransecting bulbar urethroplasty for urethral stricture: a systematic review and meta-analysis

BACKGROUND

Sexual function after urethroplasty may be a concern for patients, but there are still some controversies regarding the consequences of nontransecting bulbar urethroplasty (ntBU) in terms of erectile dysfunction (ED).

AIM

This meta-analysis aimed to compare the efficacy and safety of ntBU with that of transecting bulbar urethroplasty (tBU).

METHODS

The PubMed, Web of Science, Cochrane, and Embase databases were searched and reviewed up to October 31, 2022. Quality evaluation was performed using the Newcastle-Ottawa scale system and Cochrane tools for the nonrandomized and randomized studies, respectively. Baseline characteristics, preoperative information, and postoperative outcomes were collected.

OUTCOMES

Outcomes included success rate, ED, overall complication, and maximum urinary flow.

RESULTS

Thirteen studies comprising 1683 patients met the inclusion criteria, with 596 and 1087 patients undergoing ntBU and tBU, respectively. The results revealed that compared with the tBU group, the patients who underwent ntBU had a significantly lower incidence of ED, while there were no significant differences in the other perioperative outcomes. In subgroup analysis, the nontransecting anastomotic urethroplasty group had a lower incidence of ED than excision and primary anastomosis, and other perioperative outcomes were similar between the 2 groups.

CLINICAL IMPLICATIONS

The results of the study may help clinicians choose procedures that protect sexual function in the treatment of urethral stricture.

STRENGTHS AND LIMITATIONS

The strength of this study is that it is, to our knowledge, the first meta-analysis to evaluate the efficacy and safety of ntBU. A limitation is that most of the included studies were retrospective cohort studies.

CONCLUSION

ntBU preserves the high efficacy of its transecting counterpart while reducing postoperative ED.

Outcomes of transecting versus non-transecting urethroplasty for bulbar urethral stricture: a meta-analysis

OBJECTIVES

To assess outcomes of transecting vs non-transecting urethroplasty for bulbar urethral stricture in terms of stricture recurrence rate, sexual dysfunction, and patient-reported outcome measures (PROMs) related to lower urinary tract (LUT) function.

METHODS

Electronic literature searches were conducted using PubMed, Cochrane Library, Web of Science and Embase databases. The studied population was limited to men with bulbar urethral stricture included in studies that compared outcomes after transecting and non-transecting urethroplasty. The main outcome appraised was the stricture recurrence rate. Additionally, the incidence of sexual dysfunction appraised in three domains (erectile function, penile complications, and ejaculatory function) and PROMs related to LUT function after transecting vs non-transecting urethroplasty were assessed. The pooled risk ratio (RR) respectively for stricture recurrence, erectile dysfunction and penile complications was calculated using a fixed-effect model with inverse variance method.

RESULTS

In all, 694 studies were screened with 72 identified as relevant. Finally, 19 studies were suitable for analysis. The pooled difference between the transecting and non-transecting groups relating to stricture recurrence was not significant. Overall, the RR was 1.06 (95% confidence interval [CI] 0.82-1.36) and the 95% CI crossed the line of no effect (line RR = 1). Overall, the RR for erectile dysfunction was 0.73 (95% CI 0.49-1.08) and the 95% CI crossed the line of no effect (line RR = 1). Overall, the RR for penile complications was 0.47 (95% CI 0.28-0.76) and the 95% CI did not cross the line of no effect (line RR = 1). Hence, the risk of penile complications was significantly lower in the non-transecting group.

CONCLUSIONS

Our analysis of available evidence indicates that both transecting and non-transecting urethroplasties, are equal in terms of the recurrence rate. On the other hand, non-transecting techniques are better in terms of sexual function, causing less penile complications.

Erectile function after different techniques of bulbar urethroplasty: does urethral transection make a difference?

PURPOSE

We aimed to compare the impact of urethral transection after different techniques of bulbar urethroplasty on erectile function outcome.

MATERIALS AND METHODS

We retrospectively reviewed the records for 245 patients who underwent different urethroplasty techniques for bulbar urethral stricture between February 2013 and January 2021. The comparison between the transecting and non-transecting cohorts included patients' demographics, clinicopathological features of the urethral stricture, post-urethroplasty erectile function, and success of urethroplasty. Outcomes were erectile function status verified by IIEF5-15 score at preoperative, three months, and 12 months post-surgery. We defined Post-urethroplasty ED as a decrease of 5 points or more.

RESULTS

The urethroplasty success rate of the entire cohort was 86.9% after a mean follow-up of 45.59 ± 21 months. Out of 245 patients, 18 (7.3%) experienced 90-day complications. Transecting bulbar urethroplasty techniques were performed in 74 patients (30.2%), while non-transecting techniques were performed in 171 patients (69.8%). there were no differences between the cohorts regarding urethroplasty success (87.8% Vs. 86.5%, Mantel-Cox test p = 0.93) or postoperative complications (8.1% Vs. 7%, p = 0.73). Transient ED was evident in the transecting cohort as reported in 8.1% compared to 2.9% for the non-transecting (p = 0.07).Still, but de novo permanent ED was comparable (4.1% Vs. 2.9%, p = 0.65), for transecting and non-transecting, respectively.

CONCLUSIONS

Unfortunately, some patients who undergo transecting techniques of bulbar urethroplasty experience transient erectile dysfunction that can improve within the first post- urethroplasty year; however, de novo permanent erectile dysfunction is uncommon after different techniques of bulbar urethroplasty and is not predisposed by urethral transection.

Tunica albuginea versus buccal mucosa graft urethroplasty for anterior urethral stricture: A prospective randomised pilot study

Objective

The objective of the study was to compare the outcome of tunica albuginea urethroplasty (TAU) and buccal mucosa graft (BMG) urethroplasty for anterior urethral stricture.

Methods

Thirty patients who met the inclusion criteria were randomised into two groups: TAU (Group A) and BMG urethroplasty (Group B). Surgical outcome was evaluated with pre- and post-operative work-up involving retrograde urethrogram, voiding cystourethrogram, uroflowmetry, and urethroscopy. Patients were followed up till 1 year.

Results

Mean duration of surgery was statistically significant between two groups (p=0.0005). Maximum urine flow rate was comparable when compared between two groups (p=0.22) but statistically significant when compared pre- and post-operatively (p<0.001). At follow-up of 1 year, the successful outcomes were 80% in Group A and 87% in Group B. A total of five patients who had unsuccessful results required redo urethroplasty. Complications were minimal in both the groups.

Conclusion

TAU provides outcomes equivalent to those of BMG urethroplasty. TAU has less operative time, easy to perform, and beneficial in patients with poor oral hygiene.

Erectile and Ejaculatory Function Following Anterior Urethroplasty: A Systematic Review and Meta-analysis

CONTEXT

The degree of change in erectile (EF) and ejaculatory function (EjF) according to validated questionnaires following anterior urethroplasty and different techniques is unclear.

OBJECTIVE

To investigate the evidence on EF and EjF evaluated via validated questionnaires following anterior urethroplasty.

EVIDENCE ACQUISITION

A systematic review (PROSPERO ID: CRD42021229797) of the literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. The PubMed and CENTRAL databases were searched on February 1, 2021, with an updated search performed on December 1, 2021. Studies evaluating EF and/or EjF using validated questionnaires in men aged ≥18 yr following anterior urethroplasty were included.

EVIDENCE SYNTHESIS

Overall, 29 studies (two randomised and 27 nonrandomised) were included. The questionnaire most commonly used to evaluate EF and EjF was the International Index of Erectile Function (IIEF) and Male Sexual Health Questionnaire (MSHQ), respectively. The incidence of postoperative erectile dysfunction (ED) was 0-38% and the mean change in EF score according to the IIEF ranged from -4.0 to 2.5. The incidence of postoperative ejaculatory dysfunction (EjD) was 7.7-67% and the mean change in EjF score according to the MSHQ-EjD was 0.7-7.0. Meta-analyses revealed a mean difference of -0.87 (95% confidence interval [CI] -1.50 to -0.23; p = 0.008) in IIEF-EF score and 1.77 (95% CI 0.61-2.93; p = 0.003) in MSHQ-EjF score following anterior urethroplasty.

CONCLUSIONS

EF and EjF may be affected following anterior urethroplasty and men should be counselled appropriately. Owing to the variation in questionnaires and cutoff scores used, EF and EjF outcomes following different urethroplasty techniques are heterogeneous, with limited data from randomised controlled trials. An agreement on questionnaires and cutoff scores should be established to allow consistent reporting. Future research should aim to investigate best approaches for minimising sexual dysfunction.

PATIENT SUMMARY

Surgical repair of the urethra (urethroplasty) used to treat narrowing of the urethra (urethral stricture) may affect erectile and ejaculatory function. Different questionnaires and definitions are used to evaluate sexual function, so it is hard to compare data. The degree of disruption can be affected by different techniques and the severity of disease.

Erectile Dysfunction in Cirrhosis: Its Prevalence and Risk Factors

Background

Erectile dysfunction (ED) is common in men with cirrhosis. The aim of this study was to assess the prevalence of ED and the factors associated with ED in men with cirrhosis.

Methods

400 men with cirrhosis [Child-Turcotte-Pugh (CTP) class A, 44.0%; CTP class B, 41.0%; and CTP class C, 15.0%] having high Karnofsky performance score, and living in a stable monogamous relationship with a female partner were included in the study. International Index of Erectile Function (IIEF) questionnaire, and Short-Form (36) Health Survey (SF-36) were used to assess erectile function and the health-related quality of life (HRQOL), respectively.

Results

ED was found in 289 (72.3%) patients. Patients with ED reported significantly lower SF-36 scores across all the eight domains of SF-36 (i.e., physical functioning score, role physical score, bodily pain score, general health perception score, vitality score, social functioning score, role emotional score, and mental health score); physical component summary score, and mental physical component summary score, compared with those without ED. On multivariate analysis, factors associated with ED were older age, longer duration of cirrhosis, CTP-C (vs. CTP-A), higher hepatic venous pressure gradient (HVPG), presence of generalized anxiety disorder (GAD), presence of major depression, and lower appendicular skeletal muscle index measured by dual-energy X-ray absorptiometry (DEXA ASMI).

Conclusion

ED is common in men with cirrhosis, and men with ED have poor HRQOL compared with those without ED. Older age, longer duration of cirrhosis, CTP-C (vs. CTP-A), higher HVPG, presence of GAD, presence of major depression, and lower DEXA ASMI are associated with ED.

Sexual dysfunctions and their treatment in liver diseases

Sexual dysfunction (SD) is a prevalent but very commonly ignored aspect in the treatment of liver diseases and cirrhosis. The etiology of SD is multifactorial and therefore treatment strategies are complex, especially in females. Phosphodiesterase inhibitors are useful and effective in erectile dysfunction in males but in females, no single drug is available for SD, therefore multimodal treatment is required depending upon the cause. The foremost and fundamental requirement in both genders is to be stress-free and have adequate control of liver diseases. Improved quality of life is helpful in improving SD and vice versa is also true. Therefore, patients suffering from liver diseases should come forward and ask for treatment for SD, and physicians should actively enquire about SD while history taking and evaluating these patients. SD results in deterioration of quality of life, and both are modifiable and treatable aspects of liver diseases, which are never addressed actively, due to social taboos and fears of SD treatment in the presence of liver diseases. The diagnosis of SD does not require costly investigations, as the diagnosis can be established based on validated questionnaires available for both genders, therefore detailed targeted history taking using questionnaires is essential. Data are emerging in this area but is still at an early stage. More studies should be dedicated to SD in liver diseases.

To Transect or Not Transect: Results from the Scandinavian Urethroplasty Study, A Multicentre Randomised Study of Bulbar Urethroplasty Comparing Excision and Primary Anastomosis Versus Buccal Mucosal Grafting

BACKGROUND

Open surgical treatment of short bulbar urethral strictures (urethroplasty) is commonly performed as transecting excision and primary anastomosis (tEPA) or buccal mucosa grafting (BMG). Erectile dysfunction and penile complications have been reported, but there is an absence of randomised trials.

OBJECTIVE

To evaluate sexual dysfunction and penile complications after urethroplasty with tEPA versus BMG.

DESIGN, SETTING, AND PARTICIPANTS

Centres in Finland, Sweden and Norway participated. Patients with a bulbar urethral stricture of ≤2 cm without previous urethroplasty were randomised. The primary endpoints were the degree of erectile dysfunction and penile complications. Follow-up was 12 mo.

INTERVENTION

Patients were randomised to either tEPA or BMG urethroplasty.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Sexual dysfunction was measured using the International Index of Erectile Function, 5-item version (IIEF-5) and a penile complications questionnaire (PCQ) designed for this study. Continuous data were analysed using analysis of covariance and categorical data were compared using a χ² test.

RESULTS AND LIMITATIONS

A total of 151 patients were randomised to either tEPA (n = 75) or BMG (n = 76). The tEPA group reported more penile complications (p = 0.02), especially reduced glans filling (p = 0.03) and a shortened penis (p = 0.001). There were no differences in postoperative IIEF-5 total scores. Recurrence rates were similar in both groups (12.9%) but the study was not designed to detect differences in recurrence rates. The PCQ is not validated, which is a limitation.

CONCLUSIONS

More patients reported penile complications after urethroplasty with tEPA than with BMG. This should be considered when choosing the operative method, and patients should be informed accordingly.

PATIENT SUMMARY

This study compared two common operations for repair of narrowing of the male urethra. Neither of the two methods seems to cause worsened erections. However, penile problems are more common after the transection technique than after the grafting technique.

Tadalafil improves erectile dysfunction and quality of life in men with cirrhosis: a randomized double blind placebo controlled trial

BACKGROUND AND AIMS

Patients with cirrhosis have high prevalence of erectile dysfunction (ED). The aim of this study was to study the efficacy and safety of tadalafil for ED in patients with cirrhosis.

METHODS

140 cirrhotic males with ED were randomized into tadalafil 10 mg daily (n = 70) or placebo (n = 70) for 12 weeks. ED was diagnosed if erectile function (EF) domain score was < 25 in International Index of Erectile Function (IIEF) questionnaire. The erectile function domain consists of six questions concerning erection frequency, erection firmness, frequency of partner penetration, frequency of maintaining erection after penetration, ability to maintain erection to completion of intercourse and confidence in achieving and maintaining erection. Primary outcome was proportion of patients having an increase in > 5 points in EF domain of the IIEF. Generalized Anxiety Disorder 7 (GAD-7) questionnaire was used for screening and severity measuring of GAD. The presence of depression was screened using the Patient Health Questionnaire (PHQ-9) and the assessment of health related quality of life was done using the Short Form (36) Health Survey.

RESULTS

At the end of 12 weeks, more patients in tadalafil group achieved > 5 points increase in the EF domain of the IIEF when compared with the placebo group [44(62.9%) vs. 21(30%), p < 0.001]. At the end of 12 weeks, patients receiving tadalafil had significantly more change in scores on the erectile function domain, orgasmic function domain, intercourse satisfaction domain, overall satisfaction domain, erection vaginal penetration rates and successful intercourse; significantly more decline in the GAD-7 and PHQ-9 scores; significantly more improvement in scores of five of the eight domains of SF-36 (general health perception, vitality score, social functioning, role emotional and mental health) and the mental component summary rates when compared with placebo. The development of side effects and the changes in HVPG were not significantly different between the two groups.

CONCLUSIONS

Tadalafil therapy may enhance erectile function, improve anxiety, depression and quality of life; and is well tolerated by men with cirrhosis (CTP score < 10) and ED. However, further larger and long-term studies are needed to confirm these results and look for rarer side effects of using tadalafil in patients with cirrhosis.

Sexual function after anterior urethroplasty: a systematic review

Background

Urethral surgery outcomes are often evaluated by assessing urinary flow and urethral patency. However, sexual consequences may appear after urethroplasty, impairing quality of life and patient’s perception of success.

The aim of this study is to assess the relationship between anterior urethral reconstruction and postoperative sexual dysfunction, including the proposed factors predicting sexual outcomes.

Methods

We searched in PubMed database using the terms: “anterior urethroplasty”, bulbar urethroplasty” or “penile urethroplasty”, and “sexual dysfunction”, “erectile function” or “ejaculation”. Articles were independently evaluated for inclusion based on predetermined criteria. Systematic data extraction was followed by a comprehensive summary of evidence.

Results

Thirty-eight studies were included for final analysis. No randomised trial on the topic was found. Urethral surgery might affect different aspects of sexual function: erectile function, ejaculatory function, penile shape and length, and genital sensitivity, leading to severe sexual dysfunction. Patient perception of sexual impairment was related to post-operative satisfaction.

Conclusions

Sexual dysfunction after anterior urethral reconstruction is an important issue that must be appropriately discussed during preoperative patient counselling. Reported outcomes after anterior urethroplasty should include sexual consequences and relevance, evaluated using validated tools.

Erectile and Ejaculatory Dysfunction After Urethroplasty

PURPOSE OF THE REVIEW

The goal of this paper was to evaluate the impact on erectile and ejaculatory function after anterior and posterior urethroplasty.

RECENT FINDINGS

With a rise in the use of urethroplasty, its impact on sexual function has come into question. For anterior urethroplasties, some degree of erectile dysfunction is common, but this tends to be transient, with most patients having a resolution of any de novo dysfunction by 12 months. Patients with posterior urethral strictures have a very high rate of erectile dysfunction prior to surgery and may show improvement after urethroplasty. Ejaculatory function tends to improve in patients due to alleviation of obstruction while some patients notice degradation in force of ejaculation. While urethroplasty has a minimal permanent effect on sexual function for most patients, there are some patients who notice improvement and others worsening. Patients should be counseled on these risks prior to urethroplasty.

The impact of post-urethroplasty erectile dysfunction on the quality of life and treatment satisfaction

Introduction

The aim of this article was to assess the influence of sexual disorders after urethroplasty on patient's quality of life (QoL) and satisfaction of treatment.

Material and methods

We studied 106 sexually active patients who underwent urethroplasty due to urethral stricture. Patients completed the Urethral Stricture Surgery - Patient Reported Outcome Measure (USS - PROM) and International Index of Erectile Function (IIEF-5) questionnaires before and after the treatment. Spearman rank correlations were used for correlation analyses. Multiple linear regression and ordinal logistic regression analyses were used for evaluating the influence of lower urinary tract symptoms (LUTS) and IIEF-5 scores on EuroQol-5D (EQ-5D) index, EuroQol-Visual Analogue Scale (EQ-VAS), and satisfaction with treatment. Both LUTS and IIEF-5 scores were independent, significant predictors of EQ-VAS in the multiple linear regression model.

Results

Mean follow-up was 9 months (3-24). Reduction of LUTS and micturition improvement in the USS-PROM questionnaire after the surgery was found in 90 patients (85%). The average IIEF-5 score in the whole group did not change significantly, but in 39 cases (37%) worsened, and in 42 (39%) improved. Spearman's rank-order correlation indicated a significant positive correlation between improvement in IIEF-5 and general QoL in EQ-5D and also a positive correlation between improvement in IIEF-5 and improvement in EQ-VAS, which was also statistically significant (rho = 0.377, p <0.001).

Conclusions

Urethral surgery can influence sexual performance. The appearance of sexual dysfunction negatively affects the patient's quality of life, regardless of the effective restoration of the urethral patency and reduction of LUTS.

Evaluation of erectile function after anastomotic vs substitutional urethroplasty for bulbar urethral stricture

Objective

Patients and methods

Results

Conclusion

Comprehensive Prospective Assessment of Patient-reported Outcomes Following Urethroplasty

OBJECTIVE

To better define patient-reported outcomes after urethroplasty. While urethroplasty is the most effective treatment for urethral stricture, the majority of outcomes are reported using surgeon-defined endpoints.

METHODS

Patients were enrolled in a prospective study evaluating patient-reported outcomes after urethroplasty from 2012 to 2018. A number of domains were assessed preoperatively and 6 months postoperatively using both validated and nonvalidated measures including satisfaction, voiding function, urinary quality of life, erectile/ejaculatory function, penile appearance/curvature, and genitourinary pain.

RESULTS

Of 357 patients completing the study, mean age was 49.7 years with mean stricture length of 4.4 cm. Total 95.9% of patients were stricture-free on 6-month cystoscopy. Eighty percent of patients reported being satisfied with surgery, while 7.3% of patients were unsatisfied. Voiding function was globally improved after urethroplasty including International Prostate Symptom Score (19.3 vs 6.0; P < .0001), urinary quality of life (4.7 vs 1.6; P < .0001), postvoid dribbling (2.7 vs 2.5; P = .04), and sitting to void (2.4 vs 1.9; P < .0001). Additionally, genitourinary pain improved postoperatively (2.2 vs 1.6; P < .0001). Mean erectile function remained unchanged (17.7 vs 17.2; P = .46) but 12.0% of patients reported new onset erectile dysfunction. Reported ejaculatory dysfunction did not change significantly postoperatively (P = .13) but 7.1% of patients reported new ejaculatory dysfunction. Total 6.7% and 3.1% of patients complained of bothersome loss of penile length or curvature, respectively.

CONCLUSION

Urethroplasty improves voiding function and genitourinary pain associated with urethral stricture. While sexual function is preserved for the majority of patients, a small proportion of patients describe new onset erectile dysfunction, penile shortening or curvature and should be counselled accordingly.

Erectile dysfunction after urethroplasty

Introduction

The aim of this study was to analyze the influence of urethroplasty on sexual function.

Material and methods

We analyzed 75 operations: 41 anastomotic, 13 labial graft, 6 thigh skin mesh graft, and 15 penile skin flap urethroplasties. The severity of erectile dysfunction was assessed in the International Index of Erectile Function (IIEF5) questionnaire, preoperatively and at least 3 months after the surgery. The appearance of possible penile deformities was also evaluated postoperatively.

Results

The etiology and location of the stricture had no impact on the erectile dysfunction in men with untreated urethral stricture. The difference in mean IIEF5 score before and after the first urethroplasty was not statistically significant (12.58 ±9.01 and 10.88 ±9.28; t(42) = 1.25, p = 0.220). The length of the stricture had no impact on the preoperative and postoperative IIEF5 score. Stricture in penile urethra caused a risk of postoperative penile curvature (p = 0.023).

Conclusions

Patients with urethral stricture have a higher rate of erectile dysfunction than healthy men. Proper therapy should not negatively affect erectile function in a significant way, regardless of the length or location of the stricture, though it may have some influence on the penile anatomy.

The effect of urethroplasty surgery on erectile and orgasmic functions: a prospective study

Objectives:

to examine the effects of urethroplasty surgery on sexual functions by taking into account age, location of stenosis, length of stenosis and surgical technique parameters.

Materials and Methods:

The prospective study was conducted between January 2015 and August 2017 with 60 cases. Patients were categorized according to age groups (19-65 / 65-75 years), surgery technique and stricture localization and length. Before the urethroplasty operation and postoperative 6th month follow-up, the international index of erectile function (IIEF) form (15 questions), was filled, the relevant domains of sexual function; erectile function (Q1,2,3,4,5,15), orgasmic function (Q9,10) and overall satisfaction (Q13,14) were assessed.

Results:

The mean age of the cases is 54 ± 13. However, preoperative IIEF, sexual satisfaction and orgasmic function averages of patients with a stenosis segment length of 1-3 cm was found to be significantly higher than that of patients with a stenosis segment length of 4-7 cm. Between stenosis segment length groups, there was no statistical difference in terms of preoperative and postoperative sexual functions. And also, there was no statistically significant change in patients’ preoperative and postoperative sexual function scores in terms of localization of stricture and surgery techniques. However, there were statistically significant change in the postoperative IIEF and sexual satisfaction averages according to preoperative averages.

Conclusion:

Our study suggests that urethroplasty surgery itself does not significantly affect erectile function, orgasmic function, and general sexual satisfaction regardless of the type of surgery, localization and length of stenosis. Besides, there was a significant decrease in erectile function in senior adults.

Outcome of buccal mucosa graft urethroplasty: a detailed analysis of success, morbidity and quality of life in a contemporary patient cohort at a referral center

BACKGROUND

To evaluate outcome of buccal mucosa graft urethroplasty (BMGU) for the treatment of urethral stricture disease, including a detailed analysis of success, morbidity and quality of life (QoL).

METHODS

Between 12/05/2008 and 07/21/2010, 187 patients with urethral stricture disease, who were treated with BMGU at our University Medical Center, received a standardized questionnaire, evaluating postoperative success, morbidity and QoL. The primary endpoint was the success, i.e., stricture recurrence-free survival plus patients' satisfaction with surgery. Secondary endpoints included erectile function, voiding symptoms, pain and health-related QoL, which were assessed with a modified Urethral Stricture Surgery Patient Reported Outcome Measure (USS PROM), including the Erectile Function domain of the International Index of Erectile Function (IIEF-EF), Incontinence Questionnaire Male Lower Urinary Tract Symptoms Module (ICIQ-MLUTS) and EuroQol-5 dimensions (EQ-5D).

RESULTS

In total, 83 patients (51.9%) completed the questionnaire. Bulbar, penile and panurethral strictures were found in 69 patients (83.1%), 13 patients (15.7%) and one patient (1.2%), respectively. The median length of the stricture was 5 cm (range: 1-16). At a median follow-up of 46 months (range: 36-54), 65 patients (78.3%) had no stricture recurrence and were satisfied with BMGU. Median scores for ICIQ-MLUTS, IIEF-EF and EQ-5D visual analogue scale were 6, 22 and 80, respectively. Based on USS PROM, postoperative improvement of QoL and satisfaction with BMGU was found in 67 patients (80.7%) and 68 patients (81.9%), respectively.

CONCLUSIONS

In patients with urethral stricture disease, BMGU offers excellent success, morbidity and QoL.

Experience with One-Stage Repair of Urethral Strictures Using the Augmented Anastomotic Repair Technique

INTRODUCTION

We report the results of augmented anastomotic repair (AAR) in the treatment of anterior urethral strictures.

MATERIAL AND METHODS

In this retrospective study, we evaluated 71 consecutive patients who had undergone AAR between June 2004 and June 2013. Medical records were reviewed to identify early postoperative complications based on the Clavien-Dindo classification (CDC). Self-developed standardized questionnaires sent to the patients and referring urologists were used to collect data on late complications (>90) days. Stricture recurrence (SR) was defined as any postoperative endoscopic or open surgical intervention on the urethra. The influence of patient demographics, stricture characteristics, and operative procedure performed on the occurrence of SR was analyzed.

RESULTS

Early postoperative complications were rare events (11.3%) with only one severe CDC complication. Late complications were reported in 46.5% cases. At a median follow-up of 17 months (range 3-114 months), however, 64 patients had no evidence of SR and required no further intervention, giving an overall success rate of 90.1%. Seven patients with SR had a higher body mass index, were older, and had been operated on by less experienced surgeon(s). Most SRs occurred within the first year after surgery.

CONCLUSIONS

AAR was an effective and safe operative technique that allowed one-stage repair in our patients with anterior urethral strictures who needed resection of the scarred urethra and otherwise were not suitable for primary anastomosis or simple substitution urethroplasty.

The effect of urethral transection on erectile function after anterior urethroplasty

PURPOSE

To prospectively assess the effect of urethral transection on erectile function after anterior urethroplasty.

METHODS

From February 2012 to December 2014, 104 patients were enrolled in a prospective study assessing erectile function (EF) after anterior urethroplasty. Participants completed the International Index of Erectile Function (IIEF) questionnaire preoperatively and 6 months postoperatively. Outcome measures were the incidence of erectile dysfunction (ED) defined by ≥5-point change in EF and mean change in the EF domain. Factors examined were urethral transection, stricture location, patient age and other demographics. Fisher's exact test, Student's t test and linear regression were used to evaluate associations when appropriate.

RESULTS

Seventeen patients were excluded because of poor EF, leaving 87 patients for analysis. Twenty-two patients (25.3 %) had urethral transection during urethroplasty, while 65 underwent non-transecting techniques (74.7 %). For the entire cohort, IIEF scores remain unchanged (20.16 versus 20.14; p = 0.98). Eighteen patients (20.7 %) developed ED, while 15 (17.2 %) experienced an improvement in EF. Urethral transection was not associated with ED (p = 0.22) or mean change in EF (-0.8 versus +0.2; p = 0.71). Stricture location was not associated with ED, but patient age ≥50 was associated with a decrease in mean postoperative EF (-2.84 versus +1.85; p = 0.04). On linear regression analysis patient age remained independently associated with adverse change in EF (p = 0.05).

CONCLUSIONS

Urethroplasty can result in a decline in erectile function in some patients but overall is associated with minimal change in erectile function. Urethral transection is not associated with adverse change in erectile dysfunction after urethroplasty however, advanced patient age is.

Sexual (Dys)function after Urethroplasty

There is a paucity of published literature on the andrological consequences of urethral repair. Until recently authors have focused mainly on technical aspects and objective results. Reported outcomes of urethral reconstruction surgery have traditionally focused only on urodynamic parameters such as flow rates. Patient reported outcome measures have largely been neglected and there is a scarcity of well conducted systematic studies on the subject. For these reasons whether the different components of sexual life are more or less affected by different types of urethral reconstruction remains largely unknown. In an attempt to clarify the available scientific evidence, the authors make a critical review of available literature, systematizing it by sexual domain and study type. Brief pathophysiological correlations are discussed.

Measuring and Predicting Patient Dissatisfaction after Anterior Urethroplasty Using Patient Reported Outcomes Measures

PURPOSE

Subjective measures of success after urethroplasty have become increasingly valuable in postoperative monitoring. We examined patient reported satisfaction following anterior urethroplasty using objective measures as a proxy for success.

MATERIALS AND METHODS

Men 18 years old or older with urethral strictures undergoing urethroplasty were prospectively enrolled in a longitudinal, multi-institutional urethroplasty outcomes database. Preoperative and postoperative assessment included questionnaires to assess lower urinary tract symptoms, pain, satisfaction and sexual health. Analyses controlling for stricture recurrence (defined as the inability to traverse the reconstructed urethra with a flexible cystoscope) were performed to determine independent predictors of dissatisfaction.

RESULTS

At a mean followup of 14 months we found a high 89.4% rate of overall postoperative satisfaction in 433 patients and a high 82.8% rate in those who would have chosen the operation again. Men with cystoscopic recurrence were more likely to report dissatisfaction (OR 4.96, 95% CI 2.07-11.90) and men reporting dissatisfaction had significantly worse uroflowmetry measures (each p <0.02). When controlling for recurrence, multivariate analysis revealed that urethra and bladder pain (OR 1.71, 95% CI 1.05-2.77 and OR 2.74, 95% CI 1.12-6.69, respectively), a postoperative decrease in sexual activity (OR 4.36, 95% CI 2.07-11.90) and persistent lower urinary tract symptoms (eg straining to urinate OR 3.23, 1.74-6.01) were independent predictors of dissatisfaction.

CONCLUSIONS

Overall satisfaction after anterior urethroplasty is high and traditional measures of surgical success strongly correlate with satisfaction. However, independently of the anatomical appearance of the reconstructed urethra, postoperative pain, sexual dysfunction and persistent lower urinary tract symptoms were predictors of patient dissatisfaction.

The relationship between erectile function and complex panurethral stricture: a preliminary investigative and descriptive study

The aim of this study was to evaluate erectile function in patients with panurethral stricture after urethral reconstruction. Totally, 65 patients were enrolled. Different urethral reconstructions were performed according to the details of urethral strictures. The erectile function was evaluated before and after surgery. The length and location of stricture and duration from initial diagnosis to operation were recorded. The International Index of Erectile Function-5 (IIEF-5) scores, the quality of life (QoL) scores and the maximal flow rate were obtained before and 3, 6, and 12 months after surgery. A significant improvement in QoL and maximal flow rate was observed 3, 6, and 12 months after surgery compared with those observed before surgery (P < 0.05). An impairment of erectile function was observed in patients with multi-site stricture 3 months after surgery (P < 0.05). Subsequently, these patients recovered 6 and 12 months after surgery. Three months after surgery, the IIEF-5 scores in patients with anterior urethral stricture were higher than those with multi-site stricture. Similar results were observed 6 and 12 months after surgery. No significant difference in age or duration from initial diagnosis to final operation was observed between patients with erectile dysfunction after surgery and patients with normal erectile function. However, a linear regressive relationship was detected between IIEF-5 scores and location of urethral stricture. Surgical reconstruction for treating panurethral strictures has limited effects on erectile function. The location of the stricture, particularly when extended to posterior urethra, was found to be associated with erectile function after surgery.

Patient-Reported Sexual Function After Staged Penile Urethroplasty

OBJECTIVE

To evaluate sexual function after staged penile urethroplasty with oral mucosal graft (OMG).

METHODS

We identified men with completed staged penile urethroplasty with OMG from the Trauma and Urologic Reconstruction Network of Surgeons database between January 1, 2010 and May 1, 2014. Our primary outcome was change in total Sexual Health Inventory for Men (SHIM) and total Male Sexual Health Questionnaire Ejaculatory Domain (MSHQ-EjD) Short Form at baseline vs after the second stage of the procedure. Second, we assessed subjective changes in penile curvature, length, and sensation.

RESULTS

Thirty-three patients were included with a mean age of 45 years and mean body mass index of 27.6 kg/m(2). Urethral strictures arose from failed hypospadias repair in 52% and lichen sclerosus in 27%. Fifty-two percent of patients reported a previous urethroplasty. The median follow-up time between the second stage procedure and postoperative questionnaires was 6.3 months (interquartile range: 3.5-13.3). There was no significant change in the total SHIM (Δ0.64, 95% confidence interval [CI]: -3.00∼1.72) and MSHQ-EjD (Δ1.55, 95% CI: -1.53∼4.63) scores preoperatively vs postoperatively. In addition, 32% reported improved and 52% no change in satisfaction with sexual intercourse (SHIM Q5). Forty percent of patients reported reduced and 45% no change in bother with ejaculation after surgery (MSHQ-EjD Q4). Men reported new penile curvature (23%), loss of penile length (55%), and altered penile sensitivity (45%) after surgery.

CONCLUSION

Patients undergoing staged penile urethroplasty with OMG are likely to have minimal changes in erectile and ejaculatory function postoperatively, although many may experience new penile curvature, reduced penile length, and/or reduced penile sensitivity.

Erectile dysfunction in urethral stricture and pelvic fracture urethral injury patients: diagnosis, treatment, and outcomes

Urethral stricture disease, pelvic fracture urethral injury (PFUI), and their various treatment options are associated with erectile dysfunction (ED). The etiology of urethral stricture disease is multifactorial and includes trauma, inflammatory, and iatrogenic causes. Posterior urethral injuries are commonly associated with pelvic fractures. There is a spectrum in the severity of both conditions and this directly impacts the treatment options offered by the surgeon. Many published studies focus on the treatment outcomes and the relatively high recurrence rates after surgical repair. This communication reviews the current knowledge of the association between ED and urethral stricture disease, as well as PFUI. The incidence, pathophysiology, and clinical ramifications of both conditions on sexual function are discussed. The treatment options for ED in those patients are reviewed and summarized.

Revision urethroplasty success is comparable to primary urethroplasty: a comparative analysis

OBJECTIVE

To assess the efficacy and complications of revision urethroplasty compared with urethroplasty-naïve controls.

MATERIALS AND METHODS

A retrospective analysis was performed of 534 urethroplasties performed by a single surgeon from August 2003 to March 2011. Patient age, stricture length, location, etiology, comorbidities, and type of surgery were recorded. Statistical comparison between the revision cohort and urethroplasty-naïve group were made using Fisher, χ(2), and unpaired t tests, with significance at P < .05 (2-tailed). The primary outcome was urethral patency assessed by cystoscopy. Secondary (subjective) outcome measures included erectile dysfunction, pain, urinary tract infection, or chordee at 6 months.

RESULTS

A total of 476 patients met inclusion criteria with completed cystoscopic follow-up. Previous urethroplasty had failed in 49 patients (10.3%). Patients undergoing revision urethroplasty were more likely to have stricture in the penile urethra (22.4%; P = .001), to have strictures exceeding 4 cm in length (71.4% vs 54.3%; P = .023), and to require tissue transfer (83.6% vs 65.1%; P = .010). Urethral patency rates did not differ significantly between naïve and revision urethroplasty cohorts, with a mean follow-up of 49.9 months (94.6% vs 91.8%; P = .518). The revision group had a higher incidence of chordee (2.7% vs 14.3%; P = .001) and urinary tract infection (3.5% vs 10.2%; P = .04). The rates of erectile dysfunction, scrotal pain, lower urinary tract symptoms, and incontinence did not differ significantly between the 2 groups.

CONCLUSION

Revision urethroplasty is an effective treatment option for recurrent stricture after urethroplasty and is comparable to results in urethroplasty-naïve patients. Patients undergoing revision urethroplasty are more likely to require tissue transfer and experience higher rates of chordee and urinary tract infection.

De novo erectile dysfunction after anterior urethroplasty: a systematic review and meta-analysis

OBJECTIVE

To evaluate the likelihood of developing de novo erectile dysfunction (ED) after anterior urethroplasty and to determine if this likelihood is influenced by age, stricture length, number of previous procedures or timing of evaluation.

MATERIALS AND METHODS

PubMed, Embase, Cochrane, and Google Scholar databases were searched for the terms 'urethroplasty', 'urethral obstruction', 'urethral stricture', 'sexual function', 'erection', 'erectile function', 'erectile dysfunction', 'impotence' and 'sexual dysfunction'. Two reviewers evaluated articles for inclusion based on predetermined criteria.

RESULTS

In a meta-analysis of 36 studies with a total of 2323 patients, de novo ED was rare, with an incidence of 1%. In studies that assessed postoperative erectile function at more than one time point, ED was transient and resolved at between 6 and 12 months in 86% of cases.

CONCLUSIONS

Men should be counselled regarding the possibility of transient or permanent de novo ED after anterior urethroplasty procedures. Increasing mean age was associated with an increased likelihood of de novo ED, but this was not statistically significant.

The impact of ventral oral graft bulbar urethroplasty on sexual life

OBJECTIVE

To evaluate the pre- and postoperative aspects of sexual life (SL) in patients with bulbar urethral stricture who underwent ventral oral graft urethroplasty.

METHODS

Between 2009 and 2010, 52 men (mean age 36 years) were enrolled in our prospective study to ascertain sexual disorders before and after surgery. The validated Male Sexual Health Questionnaire-Long Form (MSHQ-LF) was completed pre- and postoperatively; the unvalidated but adapted Post-Urethroplasty Sexual Questionnaire (PUSQ) was completed postoperatively. Data were compared using the non parametric Wilcoxon test.

RESULTS

Before urethroplasty, most of the patients reported sexual disorders, in particular reduced ejaculatory stream (85%); many of them (35%) feared the risk of a postoperative worsening in the quality of SL. After urethroplasty, nobody reported a worsened erection, while most of the patients noticed a significant improvement in erection, ejaculation, relationship with their partner, sexual activity, and desire. Modifications in the scrotoperineal sensitivity were reported by 42% and 15% noticed esthetic changes without impact on SL. All patients reported an improvement in quality of life (QOL) and were satisfied with the outcome of urethroplasty.

CONCLUSION

Urethral stricture disease may be responsible for sexual disorders that have a significant impact upon SL. Patients confessed a marked anxiety tackling urethroplasty and declared that one of their deepest fears regarded a potential further deterioration in the quality of SL. At short-term follow-up, the minimally invasive ventral graft urethroplasty does not cause sexual complications, apart from the post-ejaculation dribbling. On the contrary, this technique showed to restore SL in all its aspects.

Hybrid minimally invasive urethroplasty for pan-anterior urethral strictures: initial results

INTRODUCTION

To describe our minimally invasive hybrid technique for treating pan-anterior urethral stricture.

PATIENTS AND METHODS

From February 2009 through November 2011, 12 patients with pan-anterior urethral stricture were operated on in our unit. The bulbospongiosus muscle was mobilized on one side, and a 2.5-cm dorsolateral bulbar urethrotomy was made. A full-thickness cold knife optical internal urethrotomy was made to reach the corpus cavernosum as graft bed. A 14- to 16-cm-long, 15- to 16-mm-wide buccal/lingual mucosa graft was harvested and sutured dorsally at the site of urethrotomy, and then distally at the meatus along with meatoplasty.

RESULTS

The mean operating time was 91.66 min. The average hospital stay was 2.4 days. The Foley catheter was removed after 3 weeks. The mean Q(max) preoperatively and postoperatively was 5.5 ± 1.87 and 18.83 ± 2.04 ml/s, respectively. Our mean follow-up was 18.5 ± 6.92 (6-32) months.

CONCLUSIONS

Our hybrid technique provides good short-term results while promoting minimal urethral mobilization and graft vascularity.
