Objectives: To evaluate the MIC-KEY button vesicostomy as an alternative to indwelling suprapubic catheters (SPCs) for bladder drainage in adults., Patients and Methods: Phase II pilot study prospectively evaluating patients with indwelling SPCs that were converted to MIC-KEY buttons, or cystoscopic-guided de novo insertion, between November 2014 and February 2019. In all, 15 patients (14 female, one male) had indwelling SPCs that had conversion or attempted conversion to MIC-KEY button, and one (male) had a cystoscopic-guided de novo insertion with a history of previous suprapubic catheterisation. The mean (range) age was 44.2 (13-73) years. Catheter-related quality-of-life (C-IQoL) questionnaire data were collected at baseline and 3 months., Results: Two patients had attempted conversion but were abandoned perioperatively due to sizing issues and insertion difficulties, respectively. Three patients were subsequently converted back to a SPC; due to button sizing (18 days), leaking (3 months), and recurrent infection (13 months). The remaining 11 patients have remained well with continued drainage via the MIC-KEY button; mean (range) duration since conversion was 34.2 (5-105) months. The C-IQoL score improved 3 months after insertion, from 50.0 to 75.4. Changes were performed dependent on patient's personalised management, typically every 3 months, under local or general anaesthetic., Conclusion: The MIC-KEY button is a safe alternative to SPC drainage in adults in the short- to medium-term, in a selected cohort., (© 2019 The Authors BJU International © 2019 BJU International Published by John Wiley & Sons Ltd.)

Objectives: To present our experience of the Detour extra-anatomic stent (EAS; Porges-Coloplast, Denmark) to bypass ureteric obstruction. Use of the EAS is indicated in patients with complex ureteric strictures or malignant disease, where long-term nephrostomy drainage is undesirable., Materials and Methods: Between December 2001 and October 2017, 20 Detour EAS were implanted into 13 patients. The primary indication was ureteric obstruction or injury secondary to metastatic malignancy, or from treatment for malignancy. Five patients required bilateral EAS, with two patients having bilateral EAS following initial unilateral insertion. In 11 patients, the stent was inserted into their bladder, with 2 diverted into a double-barreled stoma. The mean age at the time of implantation was 64 years (range: 50-83 years), and the median follow-up was 12 months (range: 1.5-42 months)., Results: Four patients required stent revision for urinary leaks, and two developed recurrent urinary tract infections in their stent requiring intravenous antibiotics. All EAS continued to drain successfully following treatment or revision. One patient died due to complications from dislodgement of the stent, leading to laparotomy and intra-abdominal sepsis. Seven patients died due to progression of metastatic malignant disease, and the Detour EAS was functioning in all seven at time of death. The remaining five patients are well with functioning Detour EAS., Conclusions: The Detour EAS system provides a suitable alternative option for urinary diversion, affording a good quality of life to carefully selected patients with multiple comorbidities and malignant disease.
