Water vapor thermal therapy for indwelling urinary catheter removal in frail patients.

PURPOSE: To report the efficacy and safety of water vapor thermal therapy to achieve catheter removal in frail patients with refractory acute urinary retention. METHODS: Data from consecutive frail patients with indwelling urinary catheter undergoing the Rezum™ therapy (Boston Scientific Corporation, Marlborough, MA) at a single center between October 2017 and June 2021 were prospectively collected. The included patients were deemed unfit or at high risk of complications for conventional benign prostatic hyperplasia (BPH) surgery. Prostate volumes up to 120 mL were considered eligible. The primary endpoint was successful cessation of catheter dependency, assessed postoperatively and up to 1 year of follow-up. RESULTS: A total of 24 men met our inclusion criteria. The median age, Charlson comorbidity index, and duration of preoperative catheterization were 77 years (IQR 67-86), 6 (IQR 3-7), and 113 days (IQR 87-159), respectively. Two cases (8.3%) of postoperative complications were recorded (Clavien II and Clavien IIIa). After a median postoperative catheterization time of 21 days (IQR 11-32), all patients regained spontaneous voiding. During follow-up, two patients died and a total of 22 patients completed the 1 year follow-up. All patients maintained spontaneous voiding without recurrence of urinary retention. No surgical retreatment was performed. In terms of pharmacological management, 22/24 patients (91.7%) had a BPH medication pre-Rezum™; this decreased to 8/22 patients (36.3%) post-Rezum™ (p < 0.001). CONCLUSIONS: In this single-institution, prospective, and observational study, water vapor thermal therapy was found to be effective and safe in restoring successful spontaneous voiding in a cohort of elderly and frail patients.

Recurrent bilateral Mycobacterium bovis necrotizing epididymitis: a case report.

BACKGROUND: Mycobacterium bovis causing tuberculosis in animals is responsible for zoonotic tuberculosis in patients. Veterinary control measures and milk pasteurization has led to a significant decrease in human cases of M. bovis infections in developed countries. CASE PRESENTATION: We diagnosed recurrent M. bovis epididymitis in a 63-year old Caucasian man without any signs of pulmonary or disseminated disease. Relevant epidemiological expositions included camel milk drinking during prolonged travels in Niger, prior to initial clinical manifestations. The diagnosis was firmly established by mass spectrometry and DNA sequencing on epididymis surgical biopsy specimens. We detail therapeutic management which included surgical epididymectomy and hydrocele repair. CONCLUSION: As for other M. tuberculosis complex species, the genitourinary tract represents a frequent site of secondary dissemination and latency for M. bovis. Isolated epididymis infection is a newly documented manifestation of M. bovis disease.

Seminal vesicle invasion: what is the best adjuvant treatment after radical prostatectomy?

OBJECTIVE: • To evaluate the biochemical-failure free survival according to different adjuvant treatments in patients who underwent radical prostatectomy (RP) with seminal vesicle invasion (SVI). PATIENTS AND METHODS: • Between 1994 and 2008, 4090 men underwent RP in nine centres. Of these, 310 men had a SVI. • Exclusion criteria were: detectable postoperative prostate-specific antigen, lymph node metastases and follow-up <18 months. • Therefore, the study group included 199 patients. Of these, 41 received adjuvant radiotherapy (RT) only, 26 received adjuvant androgen deprivation therapy (ADT) only, 50 received adjuvant ADT combined with RT and 82 were monitored. The endpoint for this analysis was biochemical no evidence of disease (bNED). • Preoperative prostate-specific antigen level, specimen Gleason score, age, clinical stage, surgical margin status and adjuvant treatment were evaluated in a multivariable analysis with respect to bNED survival. RESULTS: • After a mean (range) follow-up of 60.3 (18-185) months, 88 (44.2%) patients had a biochemical relapse. • The estimated 5- and 7-year bNED survival were 32.6% and 25.9% for the observation group, 44.4% and 28.6% for the RT only group, 48.4% and 32.3% for the ADT only group and 82.8% and 62.1% for the adjuvant ADT combined with RT group. • On multivariate analysis, only adjuvant ADT combined with RT (P < 0.001) was an independent prognostic factor of biochemical relapse. CONCLUSIONS: • RP appeared to be insufficient as a single treatment for patients with SVI. • The findings of the present study suggest that adjuvant ADT combined with RT after RP for patients with SVI confers a substantial benefit on 5-year bNED survival.

[Evaluation of non-enhanced spiral CT in the assessment of renal colic: prospective series of 81 patients]. / Evaluation du scanner hélicoïdal non injecté dans la prise en charge des coliques néphrétiques: série prospective de 81 malades.

OBJECTIVE: For many years, intravenous urography has been the first-line investigation for renal colic. Since the middle of the 1990s, non-enhanced spiral CT has become a more efficient, less invasive and less expensive alternative to IVU. The aim of this study was to compare non-enhanced spiral CT and IVU in the assessment of renal colic and to evaluate the possibility of exclusive CT assessment in this disease. MATERIAL AND METHODS: Prospective study including 81 patients all undergoing urgent non-enhanced spiral CT, while the first 30 patients were investigated by non-enhanced spiral CT and IVU. RESULTS: Comparison of IVU versus CT: better sensitivity of CT for the diagnosis of renal colic (96% vs 92%) and for the detection of stones (95% vs 59%). CT diagnosis: A definitive diagnosis of renal colic was established in 72/81 patients: stone visualized in 64 cases and post colic syndrome in 8 cases, while the other 9 patients presented a non-urological abdominal disease. DISCUSSION: Comparison of our series with results reported in the literature confirms the superiority of CT over IVU with better visualization of the stone at a lower cost, with a shorter examination time, without injection and allowing the detection of non-urological disease. Analysis of CT signs emphasizes the importance of secondary signs for the diagnosis of renal colic (dilatation, perirenal or ureteric oedema, rim sign). Delayed excretion demonstrated by IVU and not directly evaluable by non-enhanced CT is no longer an argument in favour of IVU as first-line examination for the assessment of renal colic. CONCLUSION: The superiority of CT for the diagnosis of renal colic has now been demonstrated. Renal colic can now be assessed exclusively by first-line non-enhanced helical CT. IVU or contrast-enhanced CT may be indicated in rare cases when there is a doubt about the diagnosis on non-enhanced CT.
