Abstract
Androgen deprivation in combination with novel hormonal agents, docetaxel, or in combination with abiraterone/prednisone plus docetaxel or darolutamid plus docetaxel represent the standard therapeutic approach in metastatic hormone-sensitive prostate cancer (mHSPC). Patients with low-risk prostate cancer also benefit from additional radiation therapy or radical prostatectomy in terms of progression-free and overall survival. Despite favorable response rates, basically all patients will develop castration resistant prostate cancer (CRPC) within 2.5 to 4 years. In addition to systemic chemotherapy, second-line hormonal treatment of systemic application of radionuclides such as radium223 or 177Lu-PSMA represent salvage management options. However, nowadays about 50-65% of patients will develop symptoms due to local progression of prostate cancer which is the result of improved oncological outcomes with significantly prolonged survival times due to the new medical treatment options. Management of such symptomatic local progression will become more important in upcoming years so that all uro-oncologists need to be aware of the various surgical management options. Complications of the lower urogenital tract such as recurrent gross hematuria ± bladder clotting and with the necessity for red blood cell transfusions, subvesical obstruction and acute urinary retention, rectourethral or rectovesical fistulas might be managed by palliative surgery such as palliative transurethral resection of the prostate (TURP), radical cystectomy, radical cystoprostatectomy with urinary diversion, and pelvic exenteration. Symptomatic or asymptomatic obstruction of the upper urinary tract might be managed by endoluminal or percutaneous urinary diversion, ureteral reimplantation, ileal ureter replacement, or implantation of the Detour® system (Coloplast GmbH, Hamburg, Germany).

If complications of the lower urogenital tract occur, for example repetitive gross haematuria with or without bladder clotting and with the necessity for red blood cell transfusions, subvesical obstruction, acute urinary retention or rectourethral or rectovesical fistulas, these may be managed by palliative surgery such as palliative TURP, radical cystectomy, radical cystoprostatectomy with urinary diversion, and pelvic exenteration. Symptomatic or asymptomatic obstruction of the upper urinary tract can be managed by endoluminal or percutaneous urinary diversion, ureteral reimplantation, ileal ureter replacement, or implantation of a Detour system. However, an individualised and risk-adapted treatment strategy needs to be developed for each single patient to achieve an optimal therapeutic outcome with improvement of both symptoms and quality of life. In specific clinical situations, best supportive care may be an adequate option.

Abstract
PURPOSE OF REVIEW The purpose of this article is to outline the various therapeutic options of ureteral strictures. RECENT FINDINGS Ureteral strictures with consecutive hydronephrosis can be due to endourological and surgical procedures, inflammatory processes, radiation therapy as well as spontaneous passage of ureteral calculi. When planning surgical correction, stricture length, anatomical location as well as patients' characteristics like age, comorbidities and previous treatment in the peritoneal cavity, retroperitoneum or pelvis should be taken into consideration. Treatment options include not only surgical reconstruction techniques like simple stricture excision, end-to-end anastomosis, ureterolysis with omental wrapping, ureteroneoimplantation, renal autotransplantation and ureter-ileum replacement, but also minimally invasive procedures such as self-expandable thermostents and pyelovesical bypass prosthesis. SUMMARY Various therapeutic options can be offered in the treatment of ureteral strictures, potentially leading to long-term success rate of more than 90% and a rate of significant complications < 5%.

Abstract
Purpose: To independently assess upper urinary tract Memokath (MMK-051) stent outcomes in a national tertiary referral center. Materials and Methods: Two researchers, completely independent to the treating team, reviewed electronic MMK-051 stent(s) patient management records. Outcomes included time to first complication, complication(s)-severity, MMK-051 stent lifespan and change incidence, salvage therapy, further surgical intervention, and mortality. Results and Limitations: One hundred patients received 162 MMK-051 stent(s) (59% with malignant and 63% with distal ureteral obstruction [UO]) with only three lost to follow-up (FU). At 5-year mean FU, only 25 patients had complication-free original MMK-051 stents (14 alive, 11 dead). Of the remaining 75 patients, 22 had other stents, 12 had major surgery (e.g., nephrectomy), 3 became dialysis dependent, and 14 stabilized without ureteral stenting after original MMK-051 removal. Malignant obstruction patients had greater original MMK-051 stent longevity (p < 0.02), but also 20 of the 21 deaths (95%). The 72% mean 5-year stent complication rate included migration (46%), blockage (34%), nonfunctioning kidney (8%), urosepsis needing intravenous antibiotics (8%), and others (6%), including one postoperative death, one ureteral injury, and two with intractable pain. Median time to first complication was 12.5 months. Conclusions: MMK-051 stents had optimal utility in managing malignant UO and in those unfit for corrective surgery. Longer independently assessed mean 5-year outcomes review revealed much higher complication rates (72%) than previously reported. Future international metallic ureteral stent guidelines should encourage clinicians to adopt patient-centered multidisciplinary assessment and selection, with counseling plus goal-setting, and harmonized long-term protocol-based reporting, for optimized future patient safety and outcomes.

Urethral reconstruction in patients previously treated with Memokath™ urethral endoprosthesis. Actas Urol Esp 2019; 43:26-31. [PMID: 30100140 DOI: 10.1016/j.acuro.2018.05.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2018] [Accepted: 05/29/2018] [Indexed: 02/03/2023]
Abstract
PURPOSE To evaluate the role and success rate of urethral reconstruction in patients with urethral stricture previously treated with thermos-expandable Memokath™ urethral endoprosthesis. MATERIALS AND METHOD A case series of patients with urethral stricture and Memokath™ endoprosthesis treated with urethroplasty is presented. Reconstruction was decided due to stricture progression or complications derived from primary stent treatment. Age, stricture and stent length, time between stent placement and urethroplasty, mode of stent retrieval, type of urethroplasty, complications and voiding parameters before and after urethroplasty were evaluated. Successful outcome was defined as standard voiding, without need of any postoperative procedure. RESULTS Eight cases with bulbar urethra stricture were included. Memokath™ was endoscopically retrieved before urethroplasty in 6 (75%) and by open urethrotomy at the time of urethroplasty in 2 (25%). Technique of urethroplasty was dorso-lateral onlay buccal mucosa graft in 5 (62.5%) cases and excision and primary anastomosis, anastomotic urethroplasty, and dorsal onlay buccal mucosa graft in one (12.5%) case each. There was no failure at 26±21.5 months median follow-up. Total IPSS, QoL, Qmax and postvoid residual significantly improved (P<.05). The only complication presented was epididymitis and penile shortening in one patient (12.5%). CONCLUSIONS Urethroplasty after re-stricture or other complications in patients with temporary Memokath™ urethral stent is a viable and definite option of reconstruction with excellent results in the short term and few complications. One-side dorsolateral onlay buccal mucosa graft augmentation is the optimal technique for this indication.

Abstract
Introduction Ureteric strictures are well-documented complications related to surgery or radiation therapy. Minimally invasive treatment using endoscopic dilatation or laser incision is the standard practice. There are no existing guidelines on which techniques to use in the treatment of different stricture types and a paucity of data regarding long-term results. Purpose Our study aimed to retrospectively assess the long-term efficacy of minimally invasive treatment in benign and malignant ureteric strictures. Materials and methods Over a 5-year period, 2007–2012, we analyzed the data of 59 consecutive patients undergoing minimally invasive treatment for symptomatic ureteric strictures. We excluded 16 patients from final analysis due to failed access or loss to follow-up. All patients but one were treated with antegrade, retrograde balloon or catheter dilatations. Successful outcome was defined as an asymptomatic, completely catheter free patient, with stable renal function. Results 43 patients were eligible for retrospective final analysis. The largest proportion of strictures occurred following surgery combined with radiotherapy 8/43 (19%). Preoperative decompression was required in 30/43 (70%). We identified 32/43 (75%) balloon dilatations, 10/43 (23%) catheter dilatations and 1/43 (2%) laser incision. Overall success rate was 31/43 (72%). All 6 recurrences occurred within 36 months, 4 within the first 12 months. 3/6 patients were successfully re-dilated. Conclusion Minimally invasive treatment is a worthwhile alternative in strictures due to previous radiation and/or surgical treatment of malignancies. Most recurrences occurred within the first year. However, late recurrences arise; therefore, patients should be subject to long-term follow-up. Moreover, re-dilatation may be required.

Abstract
PURPOSE OF REVIEW This review focuses on the role of endoscopic treatment of ureteral stricture disease (USD) in the era of minimally invasive surgery. RECENT FINDINGS There is a relative paucity of recent literature regarding the endoscopic treatment of USD. Laser endopyelotomy and balloon dilation are associated with good outcomes in treatment-naïve patients with short (< 2 cm), non-ischemic, benign ureteral strictures with a functional renal unit. If stricture recurs, repetitive dilation and laser endopyleotomy is not recommended, as success rates are low in this scenario. Patients with low-complexity ureteroenteric strictures and transplant strictures may benefit from endoscopic treatment options, although formal reconstruction offers higher rates of success. Formal ureteral reconstruction remains the gold-standard treatment for ureteral stricture disease as it is associated with higher rates of complete resolution. However, in carefully selected patients, endoscopic treatment modalities provide a low-cost, low-morbidity alternative.
