RESUMO

OBJECTIVE: To present a narrative review of fundamental information needed to manage postoperative complications in patients who have undergone genital gender-affirming surgery (GAS). METHODS: A narrative review was performed using the following keywords: 'gender-affirming surgery', 'complications', 'emergency', 'postoperative'. Articles were included after being reviewed by two primary authors for relevance. Four clinicians with significant experience providing both primary and ongoing urological care to patients after GAS were involved in article selection and analysis. RESULTS: The most common feminising genital GAS performed is a vaginoplasty. The main post-surgical complications seen by urologists include wound healing complications, voiding dysfunction, postoperative bleeding, vaginal stenosis, acute vaginal prolapse and graft loss, rectovaginal fistula, and urethrovaginal fistula. The most common masculinising genital GAS options include metoidioplasty and phalloplasty. Complications for these surgeries include urethral strictures, urethral fistulae, and urethral diverticula. Penile implants may also accompany phalloplasties and their complications include infection, erosion, migration, and mechanical failure. CONCLUSION: Genital GAS is increasing, yet there are still many barriers that individuals face not only in accessing the surgeries, but in receiving follow-up care critical for optimal outcomes. Improved education and training programmes would be helpful to identify and manage postoperative complications. Broader cultural level changes are also important to ensure a safe, gender-inclusive environment for all patients.

RESUMO

INTRODUCTION: The aim of this study was to establish the quality of patient-facing websites advertising low-intensity shockwave therapy (LISWT) for erectile dysfunction (ED) and Peyronie's disease (PD) patients in Canada. METHODS: Canadian websites offering LIWST for ED or PD were identified using online web searches. The characteristics of these websites were reviewed, along with examining the presence of HONCode certification, assigning a brief DISCERN score (a tool designed to evaluate health information online) and readability scores. We also examined the LIWST technology advertised, as well as benefits of LIWST cited by the websites. RESULTS: Twenty-five unique websites linked to 46 clinics were identified and reviewed. Twenty-four percent of websites were run by a urologist. Other specialties offering LISWT included general practitioners, anesthesiologists, naturopaths, nurse practitioners, physiotherapists, and registered massage therapists. Twenty-four percent of the websites advertised the use of a focused shockwave generator. Forty percent of the websites had peer-reviewed references. The average brief DISCERN score was 14 (standard deviation 3.4). There was no association between the physician-or non-physician-led websites and the use of peer-reviewed references, readability scores, the number of clinic locations, or higher brief discern scores. CONCLUSIONS: LISWT is readily advertised online for ED and PD patients in Canada; however, only a minority use a focused shockwave generator. There is a wide diversity of practitioners offering LISWT. Websites offering LISWT are generally of poor quality and do not provide adequate information for patients to make educated treatment decisions.

RESUMO

OBJECTIVE: To compare the long-term outcomes of initial management of pelvic fracture urethral injury (PFUI) in a large cohort of trauma patients undergoing urethral reconstruction. MATERIALS AND METHODS: 119 patients underwent urethral reconstruction by a single surgeon for PFUI at our center between 1998-2018. We compared initial PFUI management - primary realignment vs suprapubic tube (SPT) insertion alone. Multivariable Cox proportional hazard analysis was used to assess the association between primary intervention and the risk of having a complication. RESULTS: PFUI was initially managed with primary realignment (57%) or SPT alone (43%). Ultimately, all patients underwent a primary perineal urethral anastomosis after a median of 7 months (IQR: 5-14). Overall, 27 patients (23%) had 1 or more long-term complications after a median 25 months (IQR:7-66), including urethral stricture, de novo erectile dysfunction, and urinary incontinence. On multivariable analysis, initial PFUI management did not predict for complications. CONCLUSION: No difference was found in long-term outcomes after urethral reconstruction when comparing initial PFUI management of primary realignment vs SPT insertion.

RESUMO

OBJECTIVE: To evaluate the compliance of infertile men with the use of scrotal cooling devices. As a secondary objective, sperm parameters, deoxyribonucleic acid fragmentation, and hormone profiles were examined. DESIGN: This exploratory study on scrotal cooling provided scrotal cooling devices to men with primary infertility and abnormal semen parameters. Feedback on the devices after their use was gathered in the form of a questionnaire, and semen parameters were examined after device use. SETTING: Single center infertility clinic in Toronto, Ontario, Canada. PATIENTS: Patients with primary infertility and abnormal semen parameters were prospectively evaluated before and after scrotal cooling. INTERVENTIONS: One of two scrotal cooling devices (Underdog or Snowballs) was used, on the basis of patient preference. MAIN OUTCOME MEASURES: Questionnaires were completed by patients on compliance with device use and concerns about and recommendations for improving the cooling devices. Baseline deoxyribonucleic acid fragmentation index, sperm parameters, and hormones were measured at the initial visit (t = 0) and at subsequent visits (t = 4-12 weeks). Statistical comparison of values before and after scrotal cooling was performed. RESULTS: Forty patients were enrolled in the study, and the questionnaire was completed by 65.0% (n = 26). Most respondents (76.9%) used scrotal cooling less than the recommended duration. Respondents believed that the devices were uncomfortable (31.5%), impeded work (21.0%), and lost cooling rapidly (14.3%). Significant increases in sperm motility and vitality (from 25.4 % to 29.0% and from 64.8% to 71.7%, respectively) were demonstrated after scrotal cooling. CONCLUSIONS: Most patients were not compliant with the recommended use of the scrotal cooling devices because of issues of comfort, convenience, and concealability. Further work on improving scrotal cooling devices is necessary to enhance their potential as a therapeutic tool for men with abnormal sperm parameters and infertility.

RESUMO

BACKGROUND: When technically feasible, partial nephrectomy (pN) is preferred over radical nephrectomy (rN) due to similar oncological control with preservation of renal function. Here, we evaluate the incorporation of pN into practice for small renal masses and examine the associated outcomes. METHODS: We included patients who had undergone either a partial or radical nephrectomy in Alberta, Canada for renal cell carcinomas with pathology tumor stage T1a between 2002 and 2014 (N=1449). Patients were excluded if they had multiple tumors or if they were on dialysis prior to nephrectomy. RESULTS: pN use increased over the duration of the study period. Patients treated after the introduction of guidelines (2007) recommending the use of pN were significantly more likely to receive a pN (OR: 2.709, 95% CI: 1.944-3.775; p<0.001) after adjusting for baseline estimated glomerular filtration rate (GFR), age, and sex. Patients who received rN were at significantly increased risk of death (HR: 1.528, 95% CI: 1.029-2.270; p=0.036) after controlling for baseline GFR, age, and sex. Baseline GFR significantly affected odds of receiving pN (p<0.050) in the entire cohort, but subgroup analysis of more recently diagnosed patients (2011-2014) showed that only patients with kidney failure (GFR <15) were less likely to have received pN. DISCUSSION: The utilization of pN for patients with pT1a renal cell carcinoma has increased significantly over time and has been accelerated by the introduction of guideline recommendations. Patients treated with pN over the study period had superior overall survival.

RESUMO

INTRODUCTION: Circumcision is the most common surgical procedure performed by pediatric urologists. Ketorolac has been shown to have an efficacy similar to morphine in multimodal analgesic regimens without the commonly associated adverse effects. Concerns with perioperative bleeding limit the use of ketorolac as an adjunct for pain control in surgical patients. As such, we sought to evaluate our institutional outcomes with respect to ketorolac and postoperative bleeding. METHODS: We retrospectively reviewed all pediatric patients undergoing circumcision from January 1, 2014 to December 31, 2015 at the Alberta Children's Hospital. Demographics, perioperative analgesic regimens, and return to emergency department or clinic for bleeding were gathered through chart review. RESULTS: A total of 475 patients undergoing circumcisions were studied, including 150 (32%) who received perioperative ketorolac and 325 (68%) who received standard analgesia. Patients receiving ketorolac were more likely to return to the emergency department or clinic for bleeding (ketorolac group 19/150 [13%], non-ketorolac group 16/325 [5.0%]; p=0.005). Patients receiving ketorolac were more likely to have postoperative sanguineous drainage (ketorolac group 96/150 [64%], non-ketorolac group 150/325 [46%]; p<0.001). There was no significant difference in the number of patients requiring postoperative admission or further medical intervention. CONCLUSIONS: Although a promising analgesic, ketorolac requires additional investigation for safe usage in circumcisions due to possible increased risk of bleeding.

RESUMO

Background: A rare report of a tubulovillous adenoma arising in the setting of a dual pancreas-kidney transplant patient. Case Presentation: This adenoma was discovered in a 60-year-old male with a dual pancreas-kidney transplant that presented with urinary retention and gross hematuria. Management of this patient required both transurethral resection of the tumor as well as a laparotomy after recurrence. Follow-up with cystoscopy has shown no further recurrence of the tumor. Conclusion: This case adds to the few cases documented of adenomas arising in bladders augmented with gastrointestinal tract tissue. The tumor may reflect growth from donor duodenal graft tissue, however, the metaplasia of urothelial tissue cannot be fully ruled out. Based on this case, our understanding of these rare tumors and their clinical course is deepened.

RESUMO

Transcription activator-like effectors (TALEs), originating from the Xanthomonas genus of bacteria, bind to specific DNA sequences based on amino acid sequence in the repeat-variable diresidue (RVD) positions of the protein. By altering these RVDs, it has been shown that a TALE protein can be engineered to bind virtually any DNA sequence of interest. The possibility of multiplexing TALEs for the purposes of identifying specific DNA sequences has yet to be explored. Here, we demonstrate a system in which a TALE protein bound to a nitrocellulose strip has been utilized to capture purified DNA, which is then detected using the binding of a second distinct TALE protein conjugated to a protein tag that is then detected by a dot blot. This system provides a signal only when both TALEs bind to their respective sequences, further demonstrating the specificity of the TALE binding.
