RESUMEN

PURPOSE: Prostatic urethral lift has been an effective ejaculation sparing treatment for benign prostatic hypertrophy. The aim of this study was to evaluate the effect on male semen parameters. METHODS: Between July 2014 and January 2022, 20 young men with urinary symptoms of BPH, unresponsive to drug treatment and motivated to preserve ejaculation for eventual paternity, underwent UroLift. Semen analysis was performed before and 6 month after surgery with evaluation of pH, volume, sperm concentration, total motility, vitality and morphology according to WHO 2011. All underwent digital rectal examination, transrectal prostate ultrasound to measure prostate volume, PSA, uroflowmetry, cystoscopy and urodynamics test if necessary. Objective and subjective urinary function was scheduled at 1, 3, 6, 12 month than yearly with UFM, IPSS, IIEF-5, and MSHQ-EjD-SF. RESULTS: At a mean follow-up of 36 month (range 12 to 63), no retroejaculation or changes in seminal parameters occurred. Mean age was 44.5 (range 36.5 to 48) years. Mean operative time was 15 (range 10 to 20) min and 2.5 (range 2 to 4) implants per patients were used. At 6 month there were no difference in terms of total sperm count, volume, pH, motility, vitality, morphology, liquefaction, leucocytes (p = 0.9; p = 0.8; p = 0.7; p = 1; p = 1; p = 1; p = 0,2; p = 0.5). At last, Q-max increased by 64.4% (p = 0.001), post-void residual volume decreased by 66.6% (p = 0.016), and IPSS decreased by 60% (p < 0.001). IIEF and MSHQ-EjD-SF were preserved (p = 0.14, p = 0.4). CONCLUSIONS: UroLift appears safe technique to correct LUTS from BPH in young men desirous to preserve seminal analysis.

RESUMEN

PURPOSE: To assess self-reported urethroplasty success rates and outcomes of recent GURS fellowship graduates and compare these data to the large body of published urethroplasty outcomes literature. METHODS: A voluntary survey was distributed from June 1 to June 30, 2023 to GURS fellowship graduates of the last 5 years. Participants were surveyed on time since graduation, operative volume, outcomes, and quoted success rates for urethroplasty. Data were then analyzed using descriptive statistics, binary logistic regression, and correlative analyses. RESULTS: We received responses from 49/101 (48.5%) GURS graduates. Five-year post-graduates were most represented (44.7%). The majority (52.2%) consider 81-90% of urethroplasty successful, without significant change with years in practice. Approximately 65% quoted excision and primary anastomosis (EPA) as > 90% successful. Over half of the respondents had performed > 60 urethroplasties since graduation. Only 31.3% of respondents reported re-intervening in > 10% of their postop patients, with a weak positive correlation between years in practice and need for re-intervention (p 0.01). Nearly 20% of respondents referred patients to an external reconstructionist. CONCLUSION: Increased length of time in practice does not result in higher reported urethroplasty success rates, counseling on successful outcomes, or rates of re-intervention and complications. Our survey highlights that the traditionally used success rates for urethroplasty may not be reflective of new graduates and lower volume reconstructive surgeons in their early career.

RESUMEN

PURPOSE: To answer the question of whether it is possible to achieve complete corporal covering of the urethral closure using incomplete penile disassembly in classic bladder exstrophy. We hypothesize that mobilization of the corpora under Buck's fascia, their dorsal translocation through the incisions in Buck's fascia and suturing corporal convex sides above the urethra would allow extend corporal covering of the urethra, reducing the risk of urethra-cutaneous fistula formation. MATERIALS AND METHODS: A prospective follow-up on all boys who underwent the modified Cantwell-Ransley primary penile reconstruction was conducted. Inclusion criteria comprised bladder exstrophy closure in our institution, ensuring a postoperative follow-up period of no less than 24 months. The key innovation of the technique lies in a deep dissection of the dependent corpora under Buck's fascia, followed by their dorsal relocation through extended dorsal incisions in Buck's fascia, and limited external corporal rotation 90 degrees only at the base of the penis. RESULTS: Between November 2019 and March 2022, 18 boys aged 11 to 35 months met the inclusion criteria and underwent the modified penile reconstruction. Surgical procedures and postoperative period did not include any major complications. Total corporal covering of the urethral sutures was achieved in 15 of 18 patients. No urethra-cutaneous fistulas were observed within 2 years of follow-up. All individuals demonstrated spontaneous erections, and the absence of dorsal curvature was documented. CONCLUSION: The modified technique of incomplete penile disassembly applied in a homogenous group of patients with classic bladder exstrophy allows penile shaft elongation, improved aesthetic outcomes, preserved erections, and eliminates dorsal curvature. The technique demonstrated feasibility and reliability while maintaining positive effects on tissue circulation. The absence of urethra-cutaneous fistulae is attributed to the complete corporal covering of the urethral sutures and supports the initial hypothesis.

RESUMEN

BACKGROUND: Urethrocutaneous fistula (UCF) formation is a known complication following hypospadias repair, affecting between 5 and 70% of cases. Moreover, approximately 30% of patients experience refistulization after UCF repair. The use of extracellular matrices, such as AmnioCord, a dehydrated human umbilical cord allograft manufactured by MiMedx®, may mitigate high rates of refistulization. OBJECTIVE: To determine whether the use of AmnioCord during UCF repair is associated with reduced incidence of subsequent UCFs among pediatric patients. DESIGN, SETTING, AND PARTICIPANTS: Electronic medical records were retrospectively reviewed among 60 patients who underwent at least one UCF repair at a pediatric hospital in a large urban setting in the U.S. between January 2012-June 2018. Patients were followed through January 2024. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Adjusted generalized estimating equation regression models were used to assess the association between AmnioCord use and rates of refistulization, while controlling for confounding variables. RESULTS: The number of fistula presentations per patient ranged from one to four; 53.3% had one fistula, 30.0% had two, and 16.6% had three or more. Overall fistula repair success rate was 56.8% but significantly differed by AmnioCord use in adjusted modelling; 69.4% of cases that received AmnioCord were successfully repaired, compared to 47.2% of cases that did not receive AmnioCord. In adjusted models, patients who received AmnioCord had 2.66 times greater odds of surgical success than patients who did not receive AmnioCord (95% CI:1.13-6.24; p = 0.02). CONCLUSIONS: This study demonstrates a positive association between AmnioCord use and successful UCF closure among pediatric patients.

RESUMEN

The aim of the study was to compare the efficacy of Mathieu combined urethral plate incision (Mathieu-IP) versus onlay island flap urethroplasty in patients with distal hypospadias complicated by urethral stenosis. The clinical data of 70 patients with distal hypospadias complicated by urethral plate stenosis treated in the Department of Urology, Anhui Provincial Children's Hospital (Hefei, China), from May 2019 to May 2022, were retrospectively analyzed. Thirty-eight patients underwent Mathieu-IP (Mathieu-IP group) and 32 underwent onlay island flap urethroplasty (Onlay group). Follow-ups at 1 month, 6 months, and 12 months postoperatively assessed operative time, complications, urethral meatus morphology, and family satisfaction. The Mathieu-IP group had significantly shorter operative time (mean ± standard deviation [s.d.]: 81.58 ± 5.18 min) versus the Onlay group (mean ± s.d.: 110.75 ± 6.05 min; P < 0.05). Surgical success rates were 78.9% (Mathieu-IP group) and 75.0% (Onlay group), with no significant difference ( P > 0.05). Complications were comparable between the groups. The Mathieu-IP group resulted in a vertical slit-shaped urethral meatus in 89.5% versus 13.8% in the Onlay group ( P < 0.05). Family satisfaction with general penile appearance and skin shape showed no significant differences, but the Mathieu-IP group had higher satisfaction with meatal position ( P < 0.05). Mathieu-IP offers simplicity, safety, and shorter operative time compared to Onlay. Both the techniques effectively treat urethral plate stenosis in distal hypospadias, with reduced postoperative complications compared to tubularized incised plate urethroplasty. Mathieu-IP results in a vertical slit-shaped urethral meatus which enhances urinary stream, indicating its potential for broader adoption.

RESUMEN

INTRODUCTION: It is estimated that approximately one out of 200 boys has the diagnosis of lichen sclerosus (LS), previously referred to as BXO (balanitis xerotica obliterans). Severe progressive disease is rare however, mismanagement of urethral tissues may contribute to progression of LS. STUDY DESIGN: The current literature regarding the management of severe lichen sclerosus was reviewed alongside our management of seven patients with ages ranging from six to ten years of age with severe lichen sclerosus who required surgical intervention. These patients were identified out of a busy pediatric practice that saw 5507 patients during the four-year span. Based on the pathophysiology of lichen sclerosus, urethral anatomy, and our management an algorithm was developed for medical and surgical management. RESULTS: All patients received initial medical treatment with topical steroids. Three patients underwent urethral mobilization and serial biopsy. One of these patients with severe disease required a second distal urethral mobilization. Three patients were treated with circumcision, and one is responding well to topical steroids after complex reconstruction. None developed postoperative urethral disease. DISCUSSION: Lichen sclerosus affects squamous epithelium but can extend to unaffected tissue if traumatized via the Koebner phenomenon. There are no randomized control trials for the management of the disease. Thus, appropriate early management with avoidance of urethral dilation or incision may prevent extension down the urethra that can lead to severe stricture disease. Several authors identified this as one of the worst forms of stricture diseases to manage. Based on the pathophysiology of the disease and our 4-year experience treating patients, we propose an algorithm for management of severe lichen sclerosus in boys. The diagnosis of lichen sclerosus in boys requires a high level of suspicion, and early biopsies should be obtained if suspected. If identified before circumcision or meatotomy, initial treatment should be medical. If the patient fails topical steroid therapy, circumcision and biopsy are the initial recommended surgical approach. Optimally, a biopsy with the first meatotomy establishes the diagnosis. If the disease persists, urethral mobilization may represent a curative treatment as it advances healthy urethra and allows complete removal of distal squamous epithelium instead of traumatic repeated dilations or incisions. CONCLUSION: This paper summarizes the available literature on the management of severe LS and provides a flow diagram based on the pathophysiology of the disease and our experience sever cases.

RESUMEN

The bladder exstrophy-epispadias complex includes some of the most challenging conditions treated by pediatric urologists. They are associated with the need for multiple intricate reconstructive procedures, aimed at restoring the anatomy and function of the bladder, urethra and external genitalia. These patients often endure multiple redo reconstructive procedures to improve urinary function, sexual function and cosmesis throughout the first two decades of life. In this article, we present the 30-year experience of a single surgeon performing redo surgery for males born with epispadias and bladder exstrophy. Through detailed documentation of 6 clinical cases, we highlight technical aspects that may contribute to a successful surgical reconstruction in these patients. The article is focused specifically on patients undergoing redo epispadias repair with or without concomitant continence procedures. We make the case for complete penile disassembly with external rotation of the corpora to correct recurrent dorsal curvature; this approach also allows the surgeon to have access to the proximal urethra and bladder neck after opening the intersymphiseal scar/band. This is useful when additional procedures on the bladder, such as bladder neck tailoring, are necessary. We also highlight the importance of avoiding reverse Byars' flaps when performing skin closure, due to the resulting midline scar. Besides being associated with a poor cosmetic outcome, it can also contribute to recurrent dorsal curvature. The authors advocate for rotational skin flaps to cover the penile shaft. Correction of dorsal curvature and improved cosmesis obtained with complete penile disassembly sometimes comes at the expense of the urethra being left as a hypospadias (figure). This will require further surgeries (usually a 2-stage buccal mucosa graft), much like the treatment of proximal hypospadias. Redo epispadias surgery in males remains a challenge. The systematic approach offered by the case scenarios may help guide surgeons dealing with this difficult condition. Patient with complications after repair of classic bladder exstrophy. A) Stone retrieved from posterior urethra after complete penile disassembly. B) After opening the inter-symphiseal scar, the bladder has been opened and the bladder neck tailored. C) Complete penile disassembly has been completed with corporal bodies and urethra individualized. D,E,F) Final appearance of the repair; abdominal wall was closed with anterior rectus sheath flaps, penile skin was closed with rotational flaps and urethra ended up as a hypospadias.

RESUMEN

INTRODUCTION: Simulated paediatric surgical training is inherently advantageous and flourishing. Moreover, several working conditions resulted in reduced training hours, index and subspecialty cases encountered, and the COVID-19 pandemic affected elective surgery backlogs, hence training opportunities. Hypospadias repair is technically-demanding and requires a spectrum of dissective and reconstructive skills. We therefore aimed to test a 3D-printed silicon model for hypospadias repair, in the context of hands-on surgical training. MATERIAL AND METHODS: Twenty-Seven trainees, under the supervision of 15 instructors, completed the activity. They were given a seminar to show the relevant anatomy, and 8 key steps of the exercise: (1)-degloving; (2)-urethral plate marking; (3)-incision; (4)-tubularisation; (5)-glansplasty/glanuloplasty; (6)-dartos layer preparation; (7)-preputioplasty and (8)-skin closure. Each trainee completed a structured feedback assessment. An on-site trainer supervised and evaluated each exercise. Trainees and trainers rated the model through the above steps from unsatisfactory-(1/5) to excellent-(5/5), presented herein via cross-sectional analysis. RESULTS: Eleven-(40.7 %) trainees were in years:1-3 of specialist training, 10-(37 %) were in years:4-6, and 6-(22.2 %) were beyond year-6. Two-(7.4 %) trainees had nil-hypospadias experience, 16-(59.2 %) previously assisted in procedures or performed steps, 5-(18.5 %) performed whole procedures supervised and 4-(14.8 %) independently. Twenty-(74 %) trainees and 15-(100 %) instructors judged the model to resemble the anomaly. Seventeen-(63 %) trainees and 13-(86.6 %) instructors rated the material needle-penetrability ≥3/5, compared to human tissue. Sixteen-(59 %) trainees and 13-(86.6 %) instructors rated the material suture holding ≥3/5. Eleven-(73.3 %) trainees and 13-(86.6 %) instructors rated sutures' evenness and edge coaptability ≥3/5. DISCUSSION: Hypospadias is an index operation, which requires precision skills. Simulated training in Paediatric Surgery and Urology is gaining importance. 3D-printed models are gaining a key role in simulated training. The study presents a novel 3D-printed high-fidelity silicon-based hypospadias model designed for hands-on training. A structured pathway to divide a standard hypospadias repair into key steps is displayed to ensure skill acquisition and stabilisation. CONCLUSION: This 3D-printed silicon-based hypospadias model is proven useful for hands-on training. The fidelity can still improve, especially regarding suture holding of the material. LEVEL OF EVIDENCE: LEVEL III.

RESUMEN

BACKGROUND: Most parents have anxiety before a pediatric surgical procedure. Parental anxiety may impair the parents' ability to cope with new or stressful situations while their children are undergoing surgery. By effectively improving the education of parents regarding the diagnosis, treatment, and potential complications of hypospadias and surgical repair, it might be feasible to reduce their anxiety during this process. OBJECTIVE: To determine whether structured audiovisual information would reduce parents' anxiety levels compared to classic verbal information. MATERIAL AND METHODS: The diagnosis was made and, treatment options were explained, and State-Trait Anxiety Inventory Form - State Anxiety (STAI-I) forms were filled out by parents at the first consultation. In the second consultation, parents were divided into structured audio-visual-information (Group-1) and classic verbal information (Group-2) groups. Following these consultations, all parents in both groups filled out STAI-I again. Parents filled out the forms for the last time on the postoperative-14th-day and the results were compared. RESULTS: A total of 124 (51.2%) parents were informed with structured-audiovisual-informational material and 118 parents (48.8%) were informed with classic verbal information. First STAI-I scores were 57.65 ± 5.17 and 56.91 ± 5.28 for Group-1 and Group-2, respectively, and there was no difference between the groups (p = 0.709). The STAI-I scores after the second consultation were 44.82 ± 5.65 and 49.42 ± 2.81 for Group-1 and Group-2, respectively. Parental anxiety decreased in both groups following the second consultation. Notably, a statistically significant superiority was found between the groups in favor of Group-1 (p = 0.001). DISCUSSION: Parents whose children will undergo hypospadias surgery experience significant anxiety. We observed that informing patients adequately and in appropriate language using a suitable method was associated with less anxiety. Preoperative parental anxiety is influenced by several variables, including parent age, parent gender, child age, lack of knowledge, and concerns over complications or pain. Although we are unable to alter the factors of child age and parent gender, we can impact parents' concerns regarding postoperative pain and anesthesia by enhancing their comprehension of the procedure via providing them of sufficient and accurate information. CONCLUSION: Providing parents with structured audio-visual information about the preoperative and postoperative period before hypospadias surgery is associated with lower parental anxiety levels. Supplying structured audiovisual information regarding the preoperative and postoperative periods can help parents have an improved comprehension of the procedure and minimize their anxiety.

RESUMEN

A urethral stricture is an abnormal narrowing of the urethra due to spongiofibrosis of the urethral mucosa and the underlying corpus spongiosum. The diagnostics include uroflowmetry, sonography and radiology. For penile strictures the success rate of endoscopic treatment is low. Therefore, urethroplasty should always be performed, preferably using oral mucosa. Depending on the complexity, reconstruction must be carried out in one or multiple stages. For short bulbous strictures endoscopic treatment can primarily be carried out. In the case of recurrence urethroplasty should be carried out. The indications for urethral reconstruction are primarily given for long bulbous strictures. Depending on the length and extent of the stricture, a scar resection and end-to-end anastomosis, non-transsecting end-to-end anastomosis or augmentation urethroplasty can be performed. Perineal urethrostomy (the so-called boutonnière procedure) is a treatment option for patients with complex strictures or for patients who want a straightforward solution.

RESUMEN

OBJECTIVE: TIP is the most common preformed type of Urethroplasty. The intermediate barrier is used as a waterproofing layer to prevent fistula formation. Many tissues have been utilized as a barrier layer, with varying success rates. The search for a better intermediate layer will continue. In this study, we aim to evaluate the role of Buck's Fascia as a covering for the neo-urethra to prevent fistula formation in patients who underwent Snodgrass Urethroplasty. METHODS: This prospective study was conducted between 2018 and 2022. Patients were randomly assigned to either Group 'A' or Group 'B'. Group A included patients who underwent the Snodgrass procedure with a Buck's Fascia cover, while Group B included patients whose neo-urethra was covered with the dartos flap. These patients were closely monitored for the development of short- and long-term complications in both groups, and the results were recorded. RESULTS: The study involved 164 patients, who underwent midpenile and distal hypospadias repair using the Snodgrass technique. In Group 'A' (84 patients), the neo-urethra was covered with Buck's Fascia, while in Group 'B' (80 patients), the neo-urethra was covered with the dartos flap. The mean age of the children was (23.06 ± 16.12) months in group 'A' & (26.06 ± 14.07) months in group 'B'. mean operating time was (40 ± 11.43) minutes, in Group 'A', and (70 ± 17.43) minutes, in Group 'B'. Meatal stenosis occurred in 3.57% of children in Group 'A' and 10% of patients in Group 'B'. Urethral fistulas were encountered in 2.35% of cases in Group 'A'and 10% in Group 'B'. The difference between the groups was statistically significant.

RESUMEN

BACKGROUND: Hypospadias phenotype assessment determines if the anatomy is favorable for reconstruction. Glans-Urethral Meatus-Shaft (GMS) has been adopted in an effort to standardize hypospadias classification. While extremely subjective, GMS has been widely used to classify the severity of the phenotype to predict surgical outcomes. The use of digital image analysis has proven to be feasible and prior efforts by our team have demonstrated that machine learning algorithms can emulate an expert's assessment of the phenotype. Nonetheless, the creation of these image recognition algorithms is highly subjective. In order to reduce a subjective input in the evaluation of the phenotype, we propose a novel approach to analyze the anatomy using digital image pixel analysis and to compare the results using the GMS score. Our hypothesis is that pixel cluster segmentation can discriminate between favorable and unfavorable anatomy. OBJECTIVE: To evaluate whether image segmentation and digital pixel analysis are able to analyze favorable vs unfavorable hypospadias anatomy in a less subjective manner than GMS score. METHODS: A total of 148 patients with different types of hypospadias were classified by 1 of 5 independent experts following the GMS score into "favorable" (GG), "moderately favorable" (GM) and "unfavorable" (GP) glans. From there, 592 images were generated using digital image segmentation. 584 were included for final analysis due to certain images being excluded for poor image quality or inadequate capture of target anatomy. For each image, the region of interest was segmented separately by two evaluators into "glans," "urethral plate," "foreskin" and "periurethral plate". The values obtained for each segmented region using machine-learning statistical pixel k-means cluster analysis were analyzed and compared to the GMS score given to that image using an ANOVA analysis. RESULTS: Analysis of image segmentation demonstrated that k-means pixel cluster analysis discriminated "favorable" vs "unfavorable" urethral plates. There was a significant difference between scores when comparing the GG and GM groups (p = 0.03) and GG and GP groups (p = 0.05). Pixel cluster analysis could not discriminate between "moderately favorable" and "unfavorable" urethral plates. CONCLUSIONS: Through our analysis, we found significant pairwise difference for different tissue qualities. Digital image segmentation and statistical k-means cluster analysis can discriminate anatomical features in a similar way to the GMS score. Future research can target discerning between different tissue qualities in an effort to predict surgical outcomes for hypospadias repair.

RESUMEN

BACKGROUND: Stress urinary incontinence in men is predominantly iatrogenic after radical prostatectomy or transurethral interventions. Current studies show that there is a deficit in the availability of surgical therapy not only in Germany. The aim of this study is to investigate in more detail the structural health care situation of surgical treatment of male stress incontinence in Germany. MATERIALS AND METHODS: The evaluation of the surgical therapy of male stress incontinence in Germany is based on the OPS (Operationen- und Prozedurenschlüssel-German procedural classification) codes from hospital quality reports from 2011-2019. RESULTS: From 2012-2019, the number of male incontinence surgeries declined from 2191 to 1445. The number of departments performing incontinence surgeries decreased from 275 to 244. In the multivariate analysis, a high number (≥ 50) of radical prostatectomies/year (RPE/year) is an independent predictor of a high-volume centre (≥ 10 procedures/year; odds ratio [OR] 6.4 [2.3-17.6]; p < 0.001). The most significant decrease was in sling surgery (from 1091 to 410; p < 0.001). Here, the number of cases decreased especially in departments that implanted a high number of slings (≥ 10 slings/year; -69%; -62.4 ± 15.5 surgeries/year; p = 0.007). In addition, the number of departments implanting slings decreased over the investigated time period (from 34 to 10; p < 0.001). This particularly affected departments that also had a low number of RPE/year (from 9 to 0; -100%). CONCLUSION: The situation of surgical treatment of male stress urinary incontinence in Germany shows a clear decline in sling implantation, especially in small departments. On the one hand, this reflects the increasingly differentiated indications for sling implantation. On the other hand, it raises the suspicion that a gap in care has developed, as the decline was not compensated for by other surgical therapies.
