RESUMO

This article provides a comprehensive discussion of 3-piece inflatable penile implant surgery when performed through an infrapubic approach in patients presenting with challenging anatomy or corporal fibrosis. The infrapubic approach is one of the primary approaches for inflatable device placement with excellent long-term functional outcomes. While the literature is rich in descriptions of infrapubic placement in the primary, uncomplicated setting, its role in the management of complex patients presenting to centers of excellence is less elucidated. In uncomplicated cases, the infrapubic approach offers several theoretical advantages including shorter operative time and quicker return to sexual function. In addition to describing specific details of our infrapubic technique and perioperative management, I discuss scenarios in which an infrapubic approach may allow for better exposure for correction of dorsal deformity, facilitate secondary surgical maneuvers such as suprapubic lipectomy, or protect existing incontinence prosthetics already in place. Specific technique and surgical pearls from our prosthetic center of excellence are reviewed for each of these challenging scenarios. Ultimately, prosthetic surgeons should be adept at placing, revising, and removing devices through both approaches so that various forms of anatomical deformity and device failures can be addressed proficiently. In addition to my own clinical reflections, a critical review was performed using the Medline database to support our statements.

RESUMO

OBJECTIVE: To describe immediate and long-term outcomes of pressure regulating balloon (PRB) placement, exchange, and extraction from the lateral retroperitoneum (LR) in male patients receiving an artificial urinary sphincter (AUS). METHODS: A retrospective chart review was performed on all patients that underwent primary AUS placement between 2006 and 2021. All patients had the PRB placed in the LR during the study period. Intraoperative complications during PRB placement, exchange, or removal, and indications for PRB revision, such as infection, erosion, or mechanical failures were analyzed. RESULTS: Five hundred forty-one patients were included in the study. All patients underwent primary implantation with no intraoperative complications including no incidents of bowel or vascular injury during PRB placement. In addition, there were no instances of intraoperative injury during PRB removal (with or without PRB replacement). After mean follow-up of 54.8months (range: 1-181months), 9 patients (1.7%) developed a reservoir-specific complication with infection (5 patients, 0.9%) being the most common issue found. The second most common type or reservoir issue was a palpable or herniated reservoir. There were 2 patients (0.4%) who herniated their reservoirs and one patient with a nonbothersome, but palpable reservoir. Lastly, there were 2 incidents (0.4%) of mechanical failure caused by a leak in the PRB. CONCLUSION: Due to the ease and safety of placing and removing PRBs from this location and exceedingly low rates of PRB-related complications in long-term follow-up, the LR should be considered as an ideal location for PRB placement in male patients receiving an AUS.

RESUMO

OBJECTIVE: To describe the role and long-term outcomes of using the 51-60cm H2O pressure regulating balloon (PRB) in male patients with an artificial urinary sphincter (AUS). METHODS: From 2005-2021, 90 patients with a variety of urethral risk factors underwent AUS placement with use of the low-pressure 51-60 cm H2O PRB to treat stress incontinence. Patient demographics, indication for use of the 51-60 cm H2O PRB, perioperative data, and postoperative outcomes were examined and Pearson's chi squared test and Wilcoxon rank sum test were used to identify associations with future revisions, erosion, and mechanical failure. RESULTS: Ninety patients were included in the study. After median follow-up of 46.6months (range: 6-146months), 4 (4.44%) patients developed an erosion-related complication that required device removal, 4 developed an infection, and 3 underwent surgery for pump relocation. One patient had a reported mechanical failure of unknown source. Thirty patients underwent revision surgery to reduce incontinence. Of the 4 patients with erosion, 1 was due to iatrogenic catheterization. The remaining 3 had numerous urethral risk factors. Univariate analysis was performed to identify predictors of cuff erosion, infection, and revision in patients with a 51-60 cm H2O PRB. No significant associations were found including prior pelvic radiation, age at AUS placement, presence of inflatable penile prosthesis (IPP), prior AUS erosion, or previous urethroplasty. CONCLUSION: The low-pressure 51-60 cm H2O PRB can be used in high-risk male patients with urinary incontinence with low rates of complications including erosion, infection, and mechanical failure. While patients may choose to undergo future revisional surgery to improve continence, the 51-60 cm H2O PRB should be considered as the initial PRB in patients with urethral risk factors.

RESUMO

BACKGROUND: Penile length loss is often observed in patients with erectile dysfunction and obesity. In patients with a prominent infrapubic fat pad, the excess fat can further reduce perceived penile length.1 As others have reported, concurrent suprapubic lipectomy and placement of a penile implant has been shown to be an effective way of exposing phallic length in this challenging patient population.2,3 OBJECTIVE: In this video, we present surgical technique and initial outcomes of concurrent suprapubic lipectomy and 3-piece inflatable penile prosthesis (IPP) placement in patients that have erectile dysfunction and lipodystrophy of the mons pubis. MATERIALS AND METHODS: We retrospectively reviewed an institutional review board-approved prosthetic database of male patients that underwent placement of a 3-piece IPP and concurrent suprapubic lipectomy from 2020 to 2023. Intraoperative complications and postoperative outcomes were collated and analyzed. To perform this operation, an elliptical incision is made around the suprapubic fat pad that extends to the base of the penis inferiorly. Laterally the incision is carried just medial to the inferior margin of the iliac crest. Sharp dissection and electrocautery are used to dissect the fat pad free. A layer of areolar tissue is preserved above the layer of the fascia to prevent seroma formation. For larger blood vessels, vascular clips are used to ensure adequate hemostasis. After removal of the fat pad, placement of the penile prosthesis can proceed as one would through an infrapubic approach. After the device is placed, the tissue flaps based on the external pudendal vessels are inspected for adequate vascularity. Penetrating towel clamps are used to approximate the skin edges from lateral to medial so that the midline closure can be approximated accurately. 0-PDS is used to anchor the flap superiorly into the lower edge of the abdominal fold. The incision is then closed in multiple layers of absorbable suture from lateral to medial. A skin stapler or suture is then used to approximate the skin and the penis is wrapped with a compressive dressing. RESULTS: Nine patients underwent the combined surgery. There were no intraoperative complications. In follow-up, 1 patient developed an infection-related complication that required device removal and immediate replacement. The remaining 8 did well postoperatively with improved dorsal phallic length with no infection or device-related complications. CONCLUSION: Concurrent suprapubic lipectomy and placement of a 3-piece IPP is a safe and reproducible technique for the treatment of suprapubic lipodystrophy, buried penis, and refractory ED.

RESUMO

PURPOSE: The Internet is a ubiquitous source of medical information, and natural language processors are gaining popularity as alternatives to traditional search engines. However, suitability of their generated content for patients is not well understood. We aimed to evaluate the appropriateness and readability of natural language processor-generated responses to urology-related medical inquiries. MATERIALS AND METHODS: Eighteen patient questions were developed based on Google Trends and were used as inputs in ChatGPT. Three categories were assessed: oncologic, benign, and emergency. Questions in each category were either treatment or sign/symptom-related questions. Three native English-speaking Board-Certified urologists independently assessed appropriateness of ChatGPT outputs for patient counseling using accuracy, comprehensiveness, and clarity as proxies for appropriateness. Readability was assessed using the Flesch Reading Ease and Flesh-Kincaid Reading Grade Level formulas. Additional measures were created based on validated tools and assessed by 3 independent reviewers. RESULTS: Fourteen of 18 (77.8%) responses were deemed appropriate, with clarity having the most 4 and 5 scores (P = .01). There was no significant difference in appropriateness of the responses between treatments and symptoms or between different categories of conditions. The most common reason from urologists for low scores was responses lacking information-sometimes vital information. The mean (SD) Flesch Reading Ease score was 35.5 (SD=10.2) and the mean Flesh-Kincaid Reading Grade Level score was 13.5 (1.74). Additional quality assessment scores showed no significant differences between different categories of conditions. CONCLUSIONS: Despite impressive capabilities, natural language processors have limitations as sources of medical information. Refinement is crucial before adoption for this purpose.

RESUMO

BACKGROUND: Sexual dysfunction (SD), including erectile (ED) and ejaculatory dysfunction, is associated with diminished quality of life (QoL) in men with UCPPS (chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) and/or interstitial cystitis/bladder pain syndrome (IC/BPS)). AIM: We sought to compare SD among male patients with UCPPS, other chronic pain conditions (positive controls, PC), and healthy controls (HC) without chronic pain, and to evaluate the association of comorbidities, psychosocial factors, and urologic factors of SD in all 3 groups. METHODS: Baseline data from male UCPPS participants, PC (irritable bowel syndrome, chronic fatigue syndrome, fibromyalgia) and HC enrolled in the Multidisciplinary Approach to the Study of Chronic Pelvic Pain (MAPP) Research Network Epidemiology and Phenotyping Study were included in the analysis. Sexual function was assessed using the International Index of Erectile Function-Erectile Function Domain (IIEFEF) and Ejaculatory Function Scale (EFS). Male ED was defined as a composite IIEF-EF score <21. Higher EFS score indicated worse sexual dysfunction; no threshold to define SD was identified for the EFS. Multivariable logistic and linear regression was used to investigate associations of comorbidities, psychosocial factors, and urologic factors with ED and ejaculatory, respectively. OUTCOMES: Comorbidities, genital pain, and psychosocial factors are associated with SD across the study population and male patients with UCPPS had a high prevalence of ED and greater ejaculatory dysfunction. RESULTS: There were 191 males with UCPPS; 44 PC; and 182 HC. Males with UCPPS had worse SD compared to PC and HC including lower mean IIEF-EF scores, greater degree of ejaculatory dysfunction, and lower quality of sexual relationships. Among all 3 cohorts, depression, stress, and pain were associated with ED in univariable and multivariable analysis, as was diabetes mellitus. Pain in the genitalia, severity of urinary symptoms, depression, stress, and history of childhood sexual trauma were associated with ejaculatory dysfunction in univariable and multivariable analysis. CLINICAL IMPLICATIONS: A multidisciplinary approach that addresses the identified risk factors for SD may improve overall QoL in males with UCPPS. STRENGTHS AND LIMITATIONS: Our study is strengthened by its use of validated, patient-reported questionnaires and inclusion of healthy and positive controls. Our understanding of the role of IC in this study is limited because only 1 patient in the study had IC/BPS as a sole diagnosis. CONCLUSIONS: When compared to healthy controls and patients with other chronic pain conditions, males with UCPPS experience higher degrees of SD, including erectile and ejaculatory dysfunction.

RESUMO

OBJECTIVE: To report sexual health outcomes in male patients undergoing open radical cystoprostatectomy using a validated questionnaire. MATERIALS AND METHODS: Beginning in 2017, male patients were asked to complete a validated questionnaire during scheduled post-cystectomy clinic visits that assessed sexual function using the 5 item International Index of Erectile Function (IIEF-5) and supplemental questions which evaluated libido, orgasm, partner interest, and adequacy of pre-operative counselling. Baseline data and functional outcomes were compared and multivariable analysis performed. RESULTS: A total of 134 patients who met inclusion criteria completed the questionnaire. Pre-operative IIEF-5 was available in 78 patients with a median score of 16 (IQR:5-23). In those patients, median age at cystectomy was 68.9 years (IQR:60.2-72.4) and median duration of follow-up was 17.3 months (IQR:6.3-28.7). Median IIEF-5 score at time of survey completion was 1 (IQR:1-11). Increasing age, shorter follow-up duration, insufficient counselling, and absence of partner interest were predictive of lower scores. Younger age, pre-operative erectile function, and neurovascular preservation were predictive of a higher IIEF-5 score on univariate and multivariate analysis. Median libido score was 2 "low" (IQR:1-3) and ability to orgasm was reported by 34 (43.6%) patients. Neurovascular preservation (OR:3.03 95% CI:1.10-8.26, P = .03) and sufficient preoperative counselling (OR:3.078 95% CI:1.17-8.098, P = .02) were associated with preserved ability to orgasm. Libido was influenced by partner interest (OR 11.7, 95% CI:3.793-6.14, P <.0001). CONCLUSION: Sexual dysfunction after radical cystoprostatectomy is prevalent with many contributing factors. As such, establishing appropriate expectations and goals during preoperative counseling, performing neurovascular preservation when appropriate, and readily identifying and treating dysfunction in follow-up may improve sexual recovery.

RESUMO

BACKGROUND: The perception of penile length loss is common in male patients undergoing radical prostatectomy; however, this has not been described after radical cystoprostatectomy (RC). AIM: To evaluate perceptions of penile length loss in male patients after RC and contributing factors. METHODS: Patients completed an institutional review board-approved questionnaire comprised the International Index of Erectile Function (IIEF-5) and supplemental questions including perceived changes in penile length after RC. Multivariable analysis was performed to determine associations between the perception of penile length loss and the amount of length lost with patient and surgery-specific factors. OUTCOMES: The rate of patient-reported penile length loss and factors contributing to this perception was the outcome of this study. RESULTS: From October 2017 to January 2019, 151 patients completed the questionnaire. The median age at cystectomy was 66.1 years (interquartile range [IQR]: 59.4-73.3), and the median duration of follow-up was 28.3 months (IQR: 13-74.1). Preoperative IIEF-5 was available in 55 patients with a median score of 14 (IQR: 3-20). The median IIEF-5 score at time of survey completion was 3 (IQR: 1-18). The majority of patients (55.1%) reported a perceived loss of penile length, 20.4% reported no loss, and 24.5% were unsure. Of those who quantified their loss in penile length, 54.6% reported losses of an inch or more. Neurovascular preservation was not found to protect against penile length loss but did correlate with a reduction in the amount reported lost (P = .008). Multivariable logistic regression analysis identified increasing IIEF-5 score at time of survey completion to protect against a perceived loss in penile length (odds ratio: 0.924, 95% confidence interval: 0.878-0.973, P = .0025), whereas increasing body mass index was associated with a loss in perceived penile length (odds ratio: 1.198, 95% confidence interval: 10.53-1.383, P = .0060). CLINICAL IMPLICATIONS: The perception of penile length loss is a commonly held belief in patients after RC, and many patients will perceive losses that exceed 1 inch (2.54 cm). STRENGTHS AND LIMITATIONS: This study is the first series to describe the perception of penile length loss after RC. It is strengthened by the study population's size, heterogeneity, and patient-reported results. It is limited by lack of objective measurements of stretched penile length. CONCLUSIONS: RC can result in significant sexual dysfunction including the perceived loss of penile length. Loh-Doyle JC, Han J, Ghodoussipour S.

RESUMO

OBJECTIVE: To identify patient and component specific factors that predispose patients to device-related complications when undergoing pressure-regulating balloon (PRB) exchange in men with an artificial urinary sphincter (AUS). METHOD: From 2009 to 2018, 55 patients underwent AUS revision with placement of a higher pressure 71-80 cm H2O PRB to treat recurrent stress incontinence. Patient demographics, perioperative data, and postoperative outcomes were examined and multivariable logistic regression analyses performed to identify predictors of erosion and mechanical failure. RESULT: After a median follow-up of 26.4 months (range: 6-103.7 months), 21 of 55 (38.1%) patients developed a device-related complication that required operative repair or removal of the AUS. Four (7.3%) patients developed erosion after the PRB pressure increase and 5 patients showed evidence of impending erosion on follow-up and underwent successful revision surgery. Twelve patients developed mechanical failure (cuff leak, n = 7; pump malfunction, n =4; unidentified fluid loss, n = 1). Multivariable logistic regression analysis found that increasing body mass index was a predictor of mechanical failure. Hypertension and lower body mass index were found to increase the risk of cuff erosion whereas radiotherapy was not. CONCLUSION: In the carefully selected patient, PRB exchange can be performed to treat recurrent incontinence in patients with an AUS, including those treated with pelvic radiotherapy. Our data suggest that this technique is susceptible to a high rate of revision surgery. As such, when revising a functional AUS system, meticulous preoperative screening, comprehensive informed consent, and follow-up protocols are essential in minimizing adverse events.

RESUMO

PURPOSE OF REVIEW: After radical cystoprostatectomy, patients often develop erectile dysfunction refractory to first- and second-line treatments. In this review, we summarize and analyze the literature describing the technical considerations and outcomes of penile implant surgery in bladder cancer patients with history of radical cystectomy and urinary diversion. RECENT FINDINGS: Penile prosthesis surgery in patients after radical cystectomy and urinary diversion has been infrequently described in the literature. Recent studies have shown that the three-piece inflatable penile prosthesis can be placed safely after significant prior intraabdominal surgery due to the development and refinement of several techniques to place the reservoir. Further studies are needed to objectively determine the impact of penile prosthetic surgery on functional outcomes in this historically undertreated yet increasingly significant patient population. As health-related quality of life outcomes continue to gain increasing importance after radical cystectomy, urologists should offer motivated bladder cancer survivors the inflatable penile prosthesis as the treatment of choice for refractory erectile dysfunction due to its safety and unmatched ability to restore erectile function.

RESUMO

OBJECTIVES: To determine the impact of radical cystectomy and orthotopic neobladder (NB) diversion on device-related outcomes in patients who undergo subsequent placement of both, an artificial urinary sphincter (AUS) and 3-piece inflatable penile prosthesis. MATERIALS AND METHODS: Using an institutional prosthetic database, we identified 39 patients who underwent radical cystectomy and NB and subsequent implantation of both prosthetic devices from 2003 to 2017. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection, mechanical failure, revision surgery, and functional outcomes were examined and compared to an appropriate matched group of patients (n = 48, non-neobladder group). RESULTS: No intraoperative complications were observed. After median follow-up of 94 months (12-177 months), 1 patient developed an infection of their penile prosthesis and 4 patients developed an erosion of their AUS. In each case, the infection did not involve the other device. Two patients required revision surgery of their penile prosthesis due to mechanical failure (reservoir leak, n = 1; cylinder aneurysm, n = 1). Twenty-one patients underwent elective revision surgery to improve continence (cuff downsizing, n = 18; pressure-regulating balloon exchange, n = 3). There were 6 cases of AUS mechanical failure. No reservoir-related complications such as herniation or erosion were observed. Compared to the control group of non-neobladder patients, there were no significant differences in prosthetic infection, mechanical failure, and revision surgery. CONCLUSION: The AUS and 3-piece inflatable penile prosthesis can coexist safely in patients with NB without an increased risk of device-related complications.

RESUMO

AIM: We report the rates of artificial urinary sphincter (AUS) mechanical failure in a contemporary cohort of patients stratified by component type and size to determine if the 3.5-cm cuff is at higher risk of failure. METHODS: From 2005-2016, a total of 486 male patients with stress incontinence underwent implantation or revision of an AUS. 993 individual cases were retrospectively reviewed (465 primary placements and 528 revisions). Components were separately tallied and cases of mechanical failure were identified. Multiple variables including duration until failure and follow-up interval were collected and analyzed for each malfunction. RESULTS: After median follow-up of 31.5 months, there were 48 distinct cases of mechanical failure. The urethral cuff was the most common component to fail (n = 27, 56.3%), followed by the pressure regulating balloon (PRB) (n = 6, 12.5%), tubing (n = 6, 12.5%), and the control pump, (n = 5, 10.4%). Four (8.3%) cases did not have the source of malfunction identifiable in available records though fluid loss was evident at the time of device interrogation. Sub-analyses of cuff failure events showed that the 3.5-cm cuff had a statistically significant higher risk of failure (HR: 7.313, (P < .0001) compared to larger cuff sizes. CONCLUSIONS: While each component is prone to malfunction, our study suggests that the 3.5-cm urethral cuff is more susceptible to failure and failure events occur earlier after placement than larger cuff sizes.

RESUMO

BACKGROUND: Pelvic radiation is a known risk factor for the development and progression of erectile dysfunction. When medical therapy fails, the 3-piece inflatable penile prosthesis (IPP) can offer patients a definitive treatment option. Because of radiation-induced vascular changes and tissue fibrosis, a careful surgical approach is necessary to avoid intraoperative complications and attain successful outcomes. Despite its widespread use in prostate cancer treatment, there are no contemporary studies examining the effects that pelvic radiation can have on 3-piece IPP placement and device survival. AIM: To present technical considerations and contemporary outcomes of placing a 3-piece IPP for refractory erectile dysfunction in patients with a history of pelvic radiation. METHODS: We retrospectively reviewed 78 patients who underwent placement of a 3-piece IPP (AMS 700; Boston Scientific, Marlborough, MA, USA) after being treated with pelvic radiotherapy from 2003 through 2016. All patients had been treated with external beam and/or brachytherapy for treatment of prostate malignancy. An infrapubic approach was used in all patients, with reservoir placement in the space of Retzius or in the lateral retroperitoneal space. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection and mechanical failure were examined and statistical analysis was performed. OUTCOMES: Rates of device infection, revision surgery, and reservoir complications. RESULTS: No intraoperative complications were observed. After a mean follow-up of 49.0 months (6.6-116.8), 2 patients developed an infection of their prosthesis that required explantation. These patients underwent successful IPP removal and immediate reimplantation. 11 patients (14.1%) required revision surgery (pump replacement, n = 4; pump relocation, n = 2; cylinder replacement, n = 4; reservoir replacement owing to leak, n = 1). No reservoir-related complications such as herniation or erosion into adjacent structures were observed. CLINICAL IMPLICATIONS: The 3-piece IPP can be placed safely in a broad range of patients treated with pelvic radiotherapy. STRENGTHS AND LIMITATIONS: This study describes contemporary long-term outcomes of the IPP in patients treated with pelvic radiation and includes patients with prior pelvic surgery and artificial urinary sphincter, which are commonly encountered in practice. It is limited by its single-center experience and lacks a comparison group of patients. Objective patient satisfaction data were not available for inclusion. CONCLUSIONS: The 3-piece IPP can be placed successfully in patients with a history of pelvic radiation without a significant increase in infectious complications, reservoir erosion, or mechanical failure compared with the global literature.

RESUMO

Paratesticular serous papillary carcinomas are very rare, with less than 40 cases reported in the literature. These neoplasms are Müllerian in origin, and more commonly seen as epithelial-type ovarian cancer. Given the rarity of this tumor in men, staging and recommended treatment options do not exist. Herein, we present the case of a 35-year-old male with high-grade invasive serous papillary carcinoma. He was diagnosed after left radical orchiectomy for paratesticular mass and subsequently treated with adjuvant chemotherapy according to existing recommendations for its ovarian counterpart. Chemotherapy was well tolerated and surveillance imaging has shown no evidence of disease. This case suggests a potential role for adjuvant therapy in patients with high-grade paratesticular serous papillary carcinoma.

RESUMO

BACKGROUND: After radical cystoprostatectomy (RC), postoperative erectile dysfunction (ED) is a common consequence with multiple contributing etiologies. The inflatable penile prosthesis (IPP) offers patients a definitive treatment option when ED is refractory to medical therapies. Because of the hostile postoperative anatomy of these patients, a careful surgical approach is necessary for successful outcomes and to avoid adjacent organ injury. To date, there is no series describing the outcomes of 3-piece IPP placement in patients with urinary diversions. AIM: To present contemporary outcomes and a description of our technique in placing a 3-piece IPP for postoperative ED in patients with a history of RC with orthotopic neobladder, ileal conduit, or continent cutaneous diversion. METHODS: We retrospectively reviewed 80 patients who underwent primary placement of a 3-piece IPP (AMS 700; American Medical Systems Inc, Minnetonka, MN, USA) after RC and urinary diversion from 2003 through 2016. 79 patients underwent RC in their treatment of urologic malignancy (71 for bladder cancer, 8 for prostate cancer) and 1 underwent RC for refractory interstitial cystitis. An infrapubic approach was used in most patients, with reservoir placement in the lateral retroperitoneal space through a counterincision medial to the anterior superior iliac spine. Patient demographics, perioperative data, and postoperative outcomes including prosthetic infection and mechanical failure were examined and statistical analysis was performed. OUTCOMES: Rates of device infection, revision surgery, and reservoir complications. RESULTS: After mean follow-up of 53.9 months (6.5-150.7 months), 4 patients developed infection of the prosthesis that required explantation. 3 of those patients underwent successful IPP reimplantation. 5 patients required revision surgery (pump replacement, n = 3; pump relocation, n = 1; cylinder replacement for cylinder aneurysm, n = 1) for mechanical failure. No statistically significant associations were found between infection and comorbidities, urinary diversion, exposure to chemotherapy, radiation, or presence of an artificial urinary sphincter. CLINICAL IMPLICATIONS: The 3-piece IPP is an effective treatment option for medication-refractory ED that can be placed safely in patients with all forms of urinary diversion. STRENGTHS AND LIMITATIONS: This study represents the 1st series that describes a successful technique and long-term outcomes of patients with urinary diversion. It is limited by its single-surgeon, single-center experience and lacks validated patient satisfaction data in follow-up. CONCLUSIONS: The 3-piece IPP, with reservoir placement in the lateral retroperitoneum, can be implanted successfully in patients with all forms of urinary diversion without a significant increase in infectious complications, reservoir erosion, or mechanical failure.

RESUMO

OBJECTIVE: To determine if the timing of radiation therapy on artificial urinary sphincter (AUS) impacts complication rates, revision rates, and number of pads per day after placement. METHODS: A retrospective review was conducted of men with prostate cancer who underwent AUS placement and radiation therapy between 1987 and 2016. RESULTS: Of 306 men, 292 (95.4%) received radiation before AUS placement (group 1) and 14 (4.6%) received radiation after AUS placement (group 2). Median follow-up was 30 months after AUS placement. Group 1 had 32 of 292 (11.0%) patients suffer from erosion, compared with 0 of 14 (0.0%) patients in group 2 (P = .191). None of the patients in group 2 had infection or mechanical failure. The number of patients who received revision in group 1 was 91 of 292 (31.2%) and in group 2 was 2 of 14 (14.3%) (P = .180). The number of pads used per day in group 1 before and after AUS placement was 5.24 ± 3.12 and 1.13 ± 1.31, respectively (P <.001). In group 2, the number of pads used per day before and after AUS placement was 6.09 ± 1.97 and 1.53 ± 0.99, respectively (P <.001). There was no significant difference in the average number of postoperative pads used per day between group 1 and group 2 (P = .907). CONCLUSION: The timing of radiation therapy does not appear to significantly affect complication rates or urinary continence, as measured in pads used after AUS placement. This multi-institutional retrospective analysis showed similar erosion and revision rates when radiation occurred after AUS placement and demonstrates preliminary safety and feasibility of the administration of radiation after AUS placement.

RESUMO

BACKGROUND: There is no contemporary scoring system to predict hospital length of stay and morbidity in Fournier's gangrene. A retrospective study was conducted to formulate a scoring system to predict duration of hospitalization, resource utilization, need for reconstruction, morbidity and mortality. METHODS: A retrospective chart review was performed on 54 patients treated for FG from 2010-2016 at LAC+USC Medical Center, the largest public hospital in Los Angeles County. Strobe guidelines were followed and the study was approved by the IRB. Predictors of LOS, morbidity, mortality and resource utilization were identified and univariate linear regressions performed to determine significance. Significant univariate predictors were used to develop a novel scoring system, the Combined Urology and Plastics Index (CUPI). The CUPI score was then compared to existing scoring systems for predicting length of stay. RESULTS: The mean patient age was 49.3, and the mean BMI was 28.6. Patients on average were hospitalized for 37.5 days, with a mean of 8.3 days in the ICU. Three patients (5.6%) died during their hospital stay, and 33 (61%) required reconstructive surgery. Multivariate logistic modeling showed that BMI (p = 0.001) and alkaline phosphatase (p < 0.001) correlated with decreasing length of stay, while age at admission was not significantly correlated (p = 0.369). Univariate analysis of existing scoring systems showed that FGSI, LRINEC, NLR, and CCI were not significantly correlated with length of stay, while the newly calculated CUPI score was shown to be a significant predictor of longer hospital stays (p = 0.001). DISCUSSION: Early emphasis on supportive care, nutrition, and involvement of reconstructive surgeons can decrease LOS in patients with Fournier's gangrene. The CUPI score on admission may be a useful tool for predicting LOS in this population.

RESUMO

OBJECTIVES: To determine patient satisfaction with testicular prostheses (TP) for testicular cancer. Reconstruction represents an important part of surgical oncology, yet placement of TP following orchiectomy is infrequently performed. Improved data on patient satisfaction with TP would help in counseling patients with testicular cancer. MATERIALS AND METHODS: Forty patients who underwent orchiectomy and TP placement for testicular cancer participated in a survey that was blinded to the providers in an outpatient clinic (2012-2014) to evaluate TP satisfaction. Categorical variables associated with satisfaction were compared using the Fisher's exact test. RESULTS: Median age at TP placement was 31 years (17-59). Most patients had their prosthesis in place for >1 year (81%) at the time of the survey. No patient reported complications from the TP and none underwent explantation. All patients felt that being offered an implant before orchiectomy was important. Overall, 33 patients (82.5%) rated the TP as good or excellent, and 35 men (87.5%) would have the prosthesis implanted again. Thirty-seven patients (92.5%) found the TP to be comfortable or very comfortable. However, 44% considered the TP too firm and 20% felt the position was not appropriate. Appropriate size, appropriate position, and TP comfort were significantly associated with good or excellent overall TP satisfaction (P < .05). CONCLUSION: Overall satisfaction with testicular implants after orchiectomy for testicular cancer is high. Patients should be offered a testicular prosthesis, especially at the time of orchiectomy. Efforts should be made to optimize implant firmness, and care should be given to proper size selection and positioning.

RESUMO

OBJECTIVE: To improve confirmation of complete tumor thrombus removal in advanced malignancy, we report on our experience using intraoperative vena cavoscopy using a flexible cystoscope to confirm complete thrombus resection. Patients with renal cell carcinoma or testicular cancer associated with inferior vena caval tumor involvement benefit from surgical resection of the primary tumor and the tumor thrombus. Intraoperative assessment of the vena cava represents a technical challenge, particularly when the thrombus is friable and involves the hepatic veins, or there is caudal extension of thrombus toward the bifurcation. MATERIAL AND METHODS: From 2006 to 2014, 36 patients underwent tumor thrombectomy and vena cavoscopy. When residual caval thrombus was suspected, a flexible cystoscope was inserted into the vena cava for direct visual inspection of the caval lumen. Perioperative outcomes including residual tumor, changes in management, and postoperative complications were analyzed. RESULTS: All patients underwent endoscopy of the caval lumen without complications. Eight of 36 (22%) patients were found to have residual tumor thrombus visualized during cavoscopy. Five of these patients had evidence of residual mass and caval invasion within the caval lumen that ultimately resulted in cavectomy. Two patients had residual tumor thrombus that was bluntly removed. One patient was found to have significant involvement of the hepatic veins. CONCLUSION: Vena cavoscopy using a flexible cystoscope is a practical technique that may be utilized intraoperatively to ensure clearance of residual thrombus burden within the inferior vena cava and to assess for caval invasion.

RESUMO

PURPOSE: Ureteral stent removal is a source of patient morbidity. We surveyed 599 patients to evaluate their experiences and identify the preferred method of stent removal. MATERIALS AND METHODS: Visitors to a kidney stone website were invited to participate. Respondents were asked how their ureteral stent was removed? Pain during and after the procedure, patient experiences, and preferences regarding stent removal were queried. Chi-square and ANOVA tests were used to identify significant differences among removal methods. RESULTS: Five hundred seventy-one respondents were included in the study. The majority of stents (44%) were removed by office cystoscopy while 39% had their stents removed by string. Mean pain during stent removal was 4.8 out of 10 with 57% reporting moderate-to-severe pain levels of 4 or more. Removal by office cystoscopy resulted in the highest experienced pain (5.3). Thirty-two percent reported delayed severe pain after stent removal, including 9% who returned for emergency care. Removal by string resulted in more emergency room visits when compared to cystoscopy. Willingness to undergo the same removal technique was lowest for those who underwent office cystoscopy and highest for operating room cystoscopy. Being informed of why a stent was placed and the removal process was of high priority for respondents. CONCLUSIONS: The majority of patients report moderate-to-severe pain with stent removal and a third report delayed significant pain after stent removal. Variations exist in the patient experience with stent removal based on the method used. More research is needed to identify effective ways to prevent or manage stent-removal-related adverse events.
