Prostate cancer in transgender women: what does a urologist need to know?

OBJECTIVE: To review of the existing literature, current guidelines and standard of practice related to prostate cancer in transgender women, as the transgender population share many of the same healthcare needs as their cisgender counterparts, but may have additional specialist needs. MATERIALS AND METHODS: We performed a non-systematic review of the literature, current guidelines and standard of practice related to prostate cancer in transgender women. RESULTS: Our search revealed 10 case reports of prostate cancer in transgender women, four specialist opinion papers, six cohort studies, and four systematic reviews. The information in these publications were assimilated to produce a review of prostate cancer in transgender women. CONCLUSION: The risk of prostate cancer in transgender women who are not on gender-affirming hormone therapy (GAHT) or who have not had gender-affirming surgery (GAS) and gender non-conforming individuals (who may never commence GAHT or have GAS) is the same as that in the cis male population. In these patients, healthcare professionals need to be able to discuss screening, diagnostic and treatment options considering future wishes for gender-affirming treatment. Prostate cancer incidence in transgender women on GAHT or following GAS is lower than age-matched cis-male counterparts, but diagnosis and treatment is more nuanced. The present review discusses the existing literature about development and incidence of prostate cancer in this population, and makes recommendations about screening, the usefulness of diagnostic tools e.g. prostate-specific antigen and magnetic resonance imaging, and considerations when formulating treatment. Potential directions for future research are discussed, which will hopefully lead to development of robust evidence-based guidelines for the diagnosis and management of prostate cancer in transgender women.

Clinical and Patient-reported Outcome Measures in Men Referred for Consideration of Surgery to Treat Lower Urinary Tract Symptoms: Baseline Results and Diagnostic Findings of the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM).

BACKGROUND: Clinical evaluation of male lower urinary tract symptoms (MLUTS) in secondary care uses a range of assessments. It is unknown how MLUTS evaluation influences outcome of therapy recommendations and choice, notably urodynamics (UDS; filling cystometry and pressure flow studies). OBJECTIVE: To report participants' sociodemographic and clinical characteristics, and initial diagnostic findings of the Urodynamics for Prostate Surgery Trial; Randomised Evaluation of Assessment Methods (UPSTREAM). UPSTREAM is a randomised controlled trial evaluating whether symptoms are noninferior and surgery rates are lower if UDS is included. DESIGN, SETTING, AND PARTICIPANTS: A total of 820 men (≥18 yr of age) seeking treatment for bothersome LUTS were recruited from 26 National Health Service hospital urology departments. INTERVENTION: Care pathway based on routine, noninvasive tests (control) or routine care plus UDS (intervention arm). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome is International Prostate Symptom Score (IPSS) and the key secondary outcome is surgery rates 18 mo after randomisation. International Consultation on Incontinence Questionnaires were captured for MLUTS, sexual function, and UDS satisfaction. Baseline clinical and patient-reported outcome measures (PROMs), and UDS findings were informally compared between arms. Trends across age groups for urinary and sexual PROMs were evaluated with a Cuzick's test, and questionnaire items were compared using Pearson's correlation coefficient. RESULTS AND LIMITATIONS: Storage LUTS, notably nocturia, and impaired sexual function are prominent in men being assessed for surgery. Sociodemographic and clinical evaluations were similar between arms. Overall mean IPSS and quality of life scores were 18.94 and 4.13, respectively. Trends were found across age groups, with older men suffering from higher rates of incontinence, nocturia, and erectile dysfunction, and younger men suffering from increased daytime frequency and voiding symptoms. Men undergoing UDS testing expressed high satisfaction with the procedure. CONCLUSIONS: Men being considered for surgery have additional clinical features that may affect treatment decision making and outcomes, notably storage LUTS and impaired sexual function. PATIENT SUMMARY: We describe initial assessment findings from a large clinical study of the treatment pathway for men suffering with bothersome urinary symptoms who were referred to hospital for further treatment, potentially including surgery. We report the patient characteristics and diagnostic test results, including symptom questionnaires, bladder diaries, flow rate tests, and urodynamics.

Long-term efficacy of polydimethylsiloxane (Macroplastique) injection for Mitrofanoff leakage after continent urinary diversion surgery.

OBJECTIVE: To assess the long-term efficacy of polydimethylsiloxane (Macroplastique) injection (MPI) in the treatment of Mitrofanoff leakage secondary to valve incompetence. PATIENTS AND METHODS: Between 1995 and 2012, the records of 24 consecutive patients who underwent MPI for Mitrofanoff urinary leakage after continent cutaneous urinary diversion (CCUD) surgery were examined. All patients had a valve deemed of sufficient length (>2 cm) to attempt Macroplastique coaptation. Treatment outcomes were divided into three categories based on physician assessment: success (dry), partial success (>50% reduction in incontinence pads) and failure. Success rates were assessed according to the type of reservoir and conduit channel. RESULTS: The mean (range) follow-up was 30 (6-96) months. One patient had initial difficulty catheterising, and subsequently required major revision surgery. In all, 12 patients (50%) failed the treatment and subsequently underwent operative revision to the channel. Three patients (12.5%) achieved complete success; one patient had an appendix channel through native bladder and the remaining two had Monti channels through colon. Nine patients (37.5%) had partial success; success rates were higher with appendix channels (four of six) and colonic reservoirs (six of seven) when compared with Monti channels (eight of 18, 44%) and ileal reservoirs (zero of two). Five of the nine patients with partial success eventually required further surgical revision for deteriorating continence at a mean (range) of 41 (14-96) months, whilst the other four have maintained sufficient continence with MPI alone. CONCLUSION: Macroplastique bulking cured only 12.5% patients, but leakage was substantially improved in a further 37.5% allowing major surgery to be avoided or postponed in one half of the cohort. Appendix Mitrofanoffs do better than the Monti Mitrofanoff, with channels through colonic segments generally doing better than those through ileal bladders. MPI should be considered as a less invasive alternative to avoid or delay major reconstructive surgery.

Male incontinence: onabotulinum toxin A and sacral nerve stimulation.

PURPOSE OF REVIEW: Overactive bladder affects 10-12% of men, of which 13% are refractory to medical therapy and seek second-line treatment. This places a substantial clinical and economic burden on the National Health Service United Kingdom. RECENT FINDINGS: This review identifies current evidence for the use of onabotulinum toxin A and sacral nerve neuromodulation for the treatment of overactive bladder in patients who do not respond to optimal medical treatment. Posterior tibial nerve stimulation is not covered here. Clinical and financial implications of the treatments are reviewed. SUMMARY: The focus will remain on recently published evidence, which may be useful to clinicians managing refractory patients.
