Benefits and Harms of Benign Prostatic Obstruction Treatments in Renal Transplanted Patients.

CONTEXT: In an increasingly ageing transplant population, timely management of benign prostatic obstruction (BPO) is key to preventing complications that result in graft dysfunction or compromise survival. OBJECTIVE: To evaluate benefits/harms of BPO treatments in transplant patients by reviewing current literature. EVIDENCE ACQUISITION: A computerised bibliographic search of Medline, Embase, and Cochrane databases was performed for studies reporting outcomes on BPO treatments in transplanted patients. EVIDENCE SYNTHESIS: A total of 5021 renal transplants (RTs) performed between 1990 and 2016 were evaluated. BPO incidence was 1.61 per 1000 population per year. Overall, 264 men underwent intervention. The mean age was 58.4 yr (27-73 yr). In all, 169 patients underwent surgery (n = 114 transurethral resection of the prostate [TURP]/n = 55 transurethral incision of the prostate [TUIP]) and 95 were treated with an un-named alpha-blocker (n = 46) or doxazosin (n = 49). There was no correlation between prostate volume and treatment modality (mean prostate size = 26 cc in the surgical group where reported and 48 cc in the medical group). The mean follow-up was 31.2 mo (2-192 mo). The time from RT to BPO treatment was reported in six studies (mean: 15.4 mo, range: 0-156 mo). The time on dialysis before RT was recorded in only three studies (mean: 47.3 mo, range: 0-288 mo). There was a mean improvement in creatinine after intervention from 2.17 to 1.77 mg/dl. A total of 157 men showed an improvement in the International Prostate Symptom Score (from 18.26 to 6.89), and there was a significant reduction in postvoid residual volume in 199 (mean fall 90.6 ml). Flow improved by a mean of 10 ml/s following intervention in 199 patients. Complications included acute urinary retention (4.1%), urinary tract infections (8.4%), bladder neck contracture (2.2%), and urethral strictures (6.9%). The mean reoperation rate was 1.4%. CONCLUSIONS: Current literature is heterogeneous and of low-level evidence. Despite this, alpha-blockers, TUIP, and TURP showed a beneficial increase in the peak urinary flow and reduced symptoms in transplants patients with BPO. Improvement in the mean graft creatinine was noted after intervention. Complications were under-reported. A multicentre comparative cohort study is needed to draw firm conclusions about the ideal treatment for BPO in RT patients. PATIENT SUMMARY: In this report, we looked at the outcomes for transplant patients undergoing medical or surgical management of benign prostatic obstruction. Although the literature was very heterogeneous, we found that medical management and surgery with transurethral resection/incision of the prostate are beneficial for improving urinary flow and bothersome symptoms. We conclude that further prospective studies are required for better clarity about timing and modality of intervention in transplant patients.

Early vs Delayed Transurethral Surgery in Acute Urinary Retention: Does Timing Make a Difference?

PURPOSE: Our goal was to compare outcomes of early vs delayed transurethral surgery for benign prostatic hyperplasia after an episode of acute urinary retention compared to men without preoperative acute retention. MATERIALS AND METHODS: We conducted a retrospective cohort analysis using data from the New York Statewide Planning and Research Cooperative System from 2002-2016. We identified men ≥40 years old who underwent primary ambulatory transurethral resection or photoselective vaporization of the prostate, assessing surgical failure as time to reoperation or recatheterization. We categorized presurgical acute urinary retention by number of episodes: none (reference), 1, or ≥2 precatheterizations, and time from first retention episode to surgery: none (reference), 0-6 months, and >6 months. We used Fine-Gray competing-risk models to predict surgical failure at 10 years, with presurgical acute retention as the primary predictor, adjusted for age, race, insurance, Charlson Comorbidity Index score, preoperative urinary infection, and procedure type, with death as the competing risk. RESULTS: Among 17,474 patients undergoing transurethral surgery, 10% had preoperative acute retention with a median time to surgery of 2.4 months (IQR: 1-18). Among men with preoperative retention, 37% had ≥6 months of delay to surgery. The 10-year cumulative treatment failure rate was 17.2% among catheter naïve men vs 34.0% with ≥2 precatheterizations and 32.9% with ≥6 months delay to surgery. Delays from catheterization to surgery were associated with higher rates of treatment failure (<6 months SHR 1.49, P < .001; ≥6 months SHR 2.11, P < .001) vs catheter naïve men. CONCLUSIONS: Preoperative acute urinary retention and delay to surgery once catheterized are associated with poorer long-term postoperative outcomes after surgery for benign prostatic hyperplasia.

Electroacupuncture protects against bladder dysfunction induced by acute urinary retention via TRPV1/ATP signaling pathway: An animal and human research study.

Electroacupuncture (EA) can protect against acute urinary retention (AUR); however, the underlying mechanism remains unclear. Non-vesicular ATP release mediated by transient receptor potential (TRP) channels were identified as a key contributor to signaling in urothelial cells. In this study, the AUR model was established by urethral outlet obstruction in female Sprague-Dawley rats. EA was performed at SP6 and BL32 for 0.5 h prior to induction of AUR. EA reduced TRPV1 expression and urinary ATP concentrations in rat bladder, decreased the peak intravesical pressure during AUR, and attenuated abnormal voiding patterns and bladder pathological injury induced by AUR. Besides, 179 patients who experienced postoperative urinary retention were recruited and found that EA reduced urinary ATP concentrations and accelerated the recovery of spontaneous voiding. These observations indicate that EA exerts protection against AUR-induced bladder dysfunction by reducing urinary ATP concentrations through the regulation of TRPV1.

Acupuncture for the Elsberg Syndrome Secondary to Varicella-Zoster Virus Infection: a Case Report and Brief Review.

Elsberg syndrome (ES) is an infectious syndrome presenting with variable signs of acute lumbosacral radiculomyelitis. Its low recognition rate leads to misdiagnosis and incorrect treatment. Thus, some ES patients may develop neurological sequelae. This case described a 74-year-old woman complained of urinary retention, constipation, and sacral numbness after herpes zoster in the perianal area. She was diagnosed with ES and accepted conventional drug treatments and urethral catheterization. The treatment was ineffective; therefore, she accepted electroacupuncture six times and her symptoms completely disappeared, with no recurrence of neurological disorders during 1-year follow-up. This shows that acupuncture is a safe and effective alternative therapy for ES. Nonetheless, further prospective studies are necessary to prove its efficacy in ES.

Perioperative Outcomes of Holmium Laser Enucleation of the Prostate: A Systematic Review.

INTRODUCTION: The aim of the study was to systematically review the literature and describe perioperative complications of holmium laser enucleation of the prostate (HoLEP), including the Clavien-Dindo classification of surgical complications. METHODS: All English language publications on HoLEP were evaluated. We followed the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) guidelines to evaluate PubMed®, Scopus®, and Web of Science™ databases from January 1, 1998, to June 1, 2020. RESULTS: Fifty-seven studies were included, for a total of 10,371 procedures. We distinguished between intra-, peri-, and postoperative complications. Overall, the rate of complications is 0-7%. Intraoperative complications include incomplete morcellation (2.3%), capsular perforation (2.2%), bladder (2.4%), and ureteric orifice (0.4%) injuries. Perioperative complications include postoperative urinary retention (0.2%), hematuria and clot retention (2.6%), and cystoscopy for clot evacuation (0.7%). Postoperative complications include dysuria (7.5%), stress (4.0%), urge (1.8%), transient (7%) and permanent (1.3%) urinary incontinence, urethral stricture (2%) and bladder neck contracture (1%). CONCLUSIONS: HoLEP is a safe procedure, with a satisfactory low complication rate. The most common reported perioperative complications are not severe (Clavien-Dindo classification grades 1-2). Further randomized studies are certainly warranted to fully determine the predictor of surgical complications in order to prevent them and improve this technique.

One-year outcomes of the ARTISAN-SNM study with the Axonics System for the treatment of urinary urgency incontinence.

AIMS: Sacral neuromodulation (SNM) is a guideline-recommended treatment for voiding dysfunction including urgency, urge incontinence, and nonobstructive retention as well as fecal incontinence. The Axonics® System is a miniaturized, rechargeable SNM system designed to provide therapy for at least 15 years, which is expected to significantly reduce revision surgeries as it will not require replacement as frequently as the non-rechargeable SNM system. The ARTISAN-SNM study is a pivotal study designed to treat patients with urinary urgency incontinence (UUI). Clinical results at 1-year are presented. METHODS: A total of 129 eligible UUI patients were treated. All participants were implanted with a quadripolar tined lead and neurostimulator in a single procedure. Efficacy data were collected using a 3-day bladder diary, a validated quality of life questionnaire (ICIQ-OABqol), and a participant satisfaction questionnaire. Therapy responders were defined as participants with ≥50% reduction in UUI episodes compared to baseline. Data were analyzed on all 129 participants. RESULTS: At 1 year, 89% of the participants were therapy responders. The average UUI episodes per day reduced from 5.6 ± 0.3 at baseline to 1.4 ± 0.2. Participants experienced an overall clinically meaningful improvement of 34 points on the ICIQ-OABqol questionnaire. All study participants (100%) were able to recharge their device at 1 year, and 96% of participants reported that the frequency and duration of recharging was acceptable. There were no serious device-related adverse events. CONCLUSIONS: The Axonics System is safe and effective at 1 year, with 89% of participants experiencing clinically and statistically significant improvements in UUI symptoms.

Catheter-associated bacterial flora in patients with benign prostatic hyperplasia: shift in antimicrobial susceptibility pattern.

BACKGROUND: Men with urinary retention secondary to benign prostatic hyperplasia (BPH) are prone to genitourinary infections. Physicians should be aware of the current antimicrobial susceptibility pattern in this population if empirical treatment is needed. The goal of this study was to evaluate variations in prevalence, composition and antimicrobial susceptibility of bacterial flora in men with indwelling catheters subjected to surgery for BPH in chosen time periods since 1994. Necessary changes in empirical therapy were also assessed. METHODS: All patients with indwelling catheters admitted to a single urological center for BPH surgery in the years 1994-1996, 2004-2006, and 2011-2015 were considered. Catheterization times and results of urine cultures from samples collected at admission were evaluated. Susceptibility for selected antimicrobials was compared separately for Gram negative and Gram positive species. For each agent and for their combinations effectiveness of empirical therapy was calculated dividing the number of patients with bacteriuria susceptible to the agents by the total number of patients with bacteriuria. RESULTS: Bacteriuria was present in 70% of 169, 72% of 132, and 69% of 156 men in the respective time periods. The incidence of Gram-positive strains increased from 10 to 37% (P < 0.001). Their susceptibility to amoxicillin/clavulanate was fluctuating (81, 61, 77%; P=NS). No vancomycin-resistant strain was present. Gram-negative flora composition was stable. Their susceptibility decreased to ciprofloxacin (70 to 53%; P = 0.01) and amoxicillin/clavulanate (56 to 37%; P < 0.01) while it increased to gentamycin (64 to 88%; P < 0.001) and co-trimoxazole (14 to 62%; P < 0.001); susceptibility to amikacin remained high (> 85%). Only two cases of resistance to carbapenems in 2004-2006 were found. In vitro effectiveness of amikacin + amoxicillin/clavulanate in empirical therapy was slowly decreasing (87 to 77%; P=NS). Imipenem was found the most effective single agent (90-95%) and its efficacy was even improved by adding vancomycin (97-98%). CONCLUSIONS: Substantial rise in the incidence of Gram-positive species and fluctuations in antimicrobial susceptibility patterns were found. Empirical therapy of genitourinary infection in catheterized men with BPH should now involve antimicrobial agents effective both to Enterococci and Enterobacteriaceae. Periodic monitoring and publishing data on antimicrobial susceptibility for this population is necessary.

Screening for depression and anxiety in patients with storage or voiding dysfunction: A retrospective cohort study predicting outcome of sacral neuromodulation.

AIMS: It has been reported that somatic treatment in patients with affective symptoms has a higher risk of failure. The aim was to investigate whether affective symptoms could predict the outcome of sacral neuromodulation (SNM) for lower urinary tract symptoms (LUTS). METHODS: All patients that underwent a SNM evaluation between 2006 and 2013 and filled out a Hospital Anxiety and Depression Score (HADS) before treatment, were included. Chi-square analysis and bivariate logistic regression were used to assess associations and predictive value. RESULTS: Eighty-six patients were included, 65 females and 21 males. Most patients, 66, had overactive bladder syndrome (OAB). The remaining 20 patients suffered from non-obstructive urinary retention (NOR). Thirty-nine OAB patients and 17 NOR patients, had a normal total HADS score before treatment. Significantly more patients showed abnormal HADS-D (P = 0.047) and HADS-A (P = 0.015) scores in the OAB group compared to the NOR group. Success of SNM could not be predicted by the HADS score P = 0.464 (after 1 year P = 0.446). Subsequent analysis revealed that an abnormal HADS score was not related to the occurrence of SNM adverse events. CONCLUSIONS: The present study did not reveal a significant relationship between an abnormal HADS score and failure of the SNM test period in a mixed group of OAB and NOR patients. However, differences between OAB and NOR patients concerning affective symptoms were present. It is known that psychological factors play a role in the severity of LUTS, but they may not predict SNM outcome. Neurourol. Urodynam. 35:1011-1016, 2016. © 2015 Wiley Periodicals, Inc.

The effect of sacral neuromodulation on pudendal nerve function and female sexual function.

AIMS: To quantify changes in pudendal nerve function with sacral neuromodulation (SNM). To understand the relationship of pudendal nerve function to SNM treatment response for overactive bladder. To assess the relationship between female sexual function and pudendal nerve function after SNM. METHODS: Women undergoing SNM between January 2010 and May 2011 were enrolled. Baseline pudendal nerve terminal motor latencies (PNTML) were measured bilaterally. Subjects underwent peripheral nerve evaluation (PNE) prior to SNM therapy. PNTML was measured at 1 and 6 weeks after sacral neuromodulator implant. Women who did not undergo permanent implantation were reassessed at the end of the 1-week PNE testing phase. Pelvic floor and sexual function questionnaires were administered at baseline and follow-up to assess pelvic floor and sexual function. RESULTS: Of 34 women enrolled, 31 were evaluated. Mean age was 67.4 ± 14.2 years with 29/34 (85.3%) treated for refractory overactive bladder. Thirty of 31 (96.7%) went on to a permanent implant. PNE success rate was 73.5% (25/33). Mean PNTML changed from 2.74 ± 0.52 msec at baseline to 2.57 ± 0.50 msec at 6 weeks postop (P = 0.198). Baseline amplitude remained stable at 1 and 6 weeks. At 6 weeks PISQ-12 scores showed improved sexual function (P = 0.034) and PFDI-20 and PFIQ-7 scores showed improved pelvic floor, colorectal and urinary symptoms (P < 0.05). CONCLUSIONS: Women with refractory overactive bladder and non-obstructive urinary retention have abnormal pudendal nerve function, which showed a non-significant trend toward improvement after SNM. Sexually active women undergoing sacral neuromodulation experienced improvement in sexual function. Quality of life improved due to improvement in urinary and colorectal function.

Pregnancy in women with Fowler's syndrome treated with sacral neuromodulation.

INTRODUCTION AND HYPOTHESIS: Our aim was to determine the impact of pregnancy on sacral neuromodulation (SNM) and vice versa in patients with Fowler's syndrome (FS), which is typified by chronic urinary retention (CUR). METHODS: We performed a retrospective study of pregnancy in patients with FS who underwent a two-stage SNM implantation. Data were obtained using a standard questionnaire and clinical interview. RESULTS: There were a total of ten patients with 13 pregnancies. The SNM was switched off in ten of the 13 pregnancies, with CUR recurring in nine of the ten pregnancies and recurrent urinary tract infections (UTI) occurring in four of these pregnancies (more than three UTI in the pregnancy). Those in whom the device was left on continued to void normally. One woman had a first trimester miscarriage, eight pregnancies went to term, and four deliveries were premature. Caesarean section was performed in eight pregnancies for obstetric reasons. Four pregnancies resulted in a vaginal delivery. There were no congenital anomalies reported. Following delivery, four of nine women experienced dysfunction of their SNM device when it was switched back on. CONCLUSION: Turing off the SNM during pregnancy results in recurrence of CUR, with an increased risk of recurrent UTI associated with preterm delivery. This did not impact foetal well-being. The option of keeping the SNM on during pregnancy should therefore be considered, and as caesarean section affects the SNM device, we advise that caesarean section should only be performed for obstetric reasons.

Acute urinary retention increases the risk of complications after transurethral resection of the prostate: a population-based study.

UNLABELLED: Study Type--Prognosis (cohort) Level of Evidence 2a. What's known on the subject? and What does the study add? Higher mortality and morbidity rates in men presenting with AUR have been reported in previous studies. This study has comprehensive comparisons of post-TURP complications between patients with and without AUR. Furthermore, it shows that AUR is associated with increased risk of complications after TURP. OBJECTIVE: • To assess the association between a history of acute urinary retention (AUR) and complications after transurethral resection of prostate (TURP). PATIENTS AND METHODS: • We conducted a retrospective, national, population-based study using Taiwan's National Health Insurance Research Database. • We included men > 50 years old, diagnosed with benign prostatic hyperplasia (BPH) and divided these into two groups: an AUR(+) group--those with AUR who underwent TURP between 2002 and 2004; and an AUR(-) group--those without AUR who underwent TURP between those dates. • Prostate cancer, Parkinsonism and multiple sclerosis were exclusion criteria. • Postoperative complications, e.g. re-catheterization, haematuria or urinary tract infection (UTI), were compared using crude odds ratios (ORs), 95% confidence intervals (CIs), and Student's t-test. • A chi-squared test was used for potential confounding factors: preoperative UTI and anticoagulant use. • Univariate and multivariate analysis on medical expenses were conducted. RESULTS: • The AUR(+) group contained 3305 men; the AUR(-) group contained 1062. • Re-catheterization (13.8%), septicaemia (1.1%) and shock (0.3%) were found only in the AUR(+) group. • The AUR(+) group had more UTIs (18.9% vs. 15.6%, OR: 1.26, 95% CI: 1.05-1.52), more lower urinary tract symptoms (22.8% vs. 16.9%, OR: 1.45, 95% CI: 1.21-1.73), fewer blood transfusions (3.2% vs. 1.5%, OR: 2.19, 95% CI: 1.29-3.72) and higher medical expenses. • There were no significant differences in haematuria, lower urinary tract stricture, or re-surgical intervention of the prostate and second-line antibiotic use. CONCLUSION: • Patients in Taiwan with BPH with AUR who were treated by TURP were associated with a higher risk of complications, longer hospital stay and more comorbidities than those without AUR and a preoperative warning is warranted for these patients.

A case of potential treatment of remote pain after sacral nerve stimulation for chronic urinary retention.

OBJECTIVE: A case is presented in which a 58-year-old man developed a potential unintended and durable treatment of pain at remote sites (cervical region and low back) after sacral nerve stimulation for chronic urinary retention. METHODS: Proper placement of the electrodes in the S3 foramen was confirmed by physiological response and fluoroscopy. RESULTS: Potential causality was shown by recurrent pain with the stimulators turned off and abatement of pain with the stimulators turned on. DISCUSSION: The current case presents a potential example of neurological crosstalk and highlights the inherent complexity in human neural physiology. Further research may reveal novel treatment strategies for patients with voiding dysfunction and chronic pain syndromes.

What are the causes and consequences of bladder overdistension? ICI-RS 2011.

AIMS: To report the outcome of the think tank on prolonged bladder overdistension from the 3rd ICI-RS meeting. METHODS: Prolonged bladder overdistension was discussed after acute urinary retention, its terminology, its prevalence, pathophysiology, and consequences, as well as prophylactic and therapeutic aspects. RESULTS: Acute prolonged bladder overdistension (ApBO) is a consequence of undetected or inadequately treated acute retention, and is mostly due to regional anesthesia, prolonged childbirth, or extensive surgery. Currently, there is no agreed terminology. A primary, temporary neurogenic detrusor dysfunction causing retention is associated with decreased or absent bladder sensation therefore patients do not complain, and management is delayed. Therapeutically, the first intervention is to drain the bladder. Recovery depends on whether reversible or irreversible damage has occurred. There are no good data to support the use of drugs or sacral neuromodulation. Intravesical electrostimulation is the only treatment that has specifically addressed this problem with encouraging results. There are no recent reports on the effect of surgery for myogenic bladder damage. CONCLUSION: ApBO is an important, but often unrecognized medical complication. There is a need for defining the terminology, for studies to record the incidence of different types of bladder overdistension, and to establish management strategies. Apart from clean intermittent self catheterization (CIC) there are no data justifying pharmacological or other therapies. Therefore, prevention is of paramount importance and there is a need to develop and test preventative strategies, which should then be incorporated in surgical registries.

Herbal medicine-induced meningitis-retention syndrome.

A 73-year-old woman developed subacute meningitis-retention syndrome (MRS), dermatitis, and latent pneumonitis likely due to the herbal medicines Shinbu-Tou and Rikkunshi-Tou. The responsible site of lesions for urinary retention seemed to be the spinal micturition pathways and, to a lesser extent, the sacral spinal cord. All of her clinical manifestations were successfully ameliorated within three weeks of discontinuation of the herbal remedies.

Técnicas regionales en traumatología del miembro inferior en cirugía mayor ambulatoria / Regional anesthesia in traumatology ambulatory surgery for lower limb

Objetivo: Revisar las diferentes técnicas de anestesia loco regionales utilizadas en cirugía traumatológica y ortopédica mayor ambulatoria, analizando las ventajas, los inconvenientes así como las complicaciones y la forma redisminuir su incidencia. Las técnicas regionales especialmente los bloqueos periféricos y la anestesia local de rodilla son una excelente opción en CMA. De las neuroaxiales la epidural tiene unos resultados muy similares a la anestesia general y la intradural deberá realizarse con dosis bajas de anestésico. El control en la perfusión de líquidos perioperatorios es un factor de relevancia en la incidencia de la retención urinaria (AU)

Objetive: To review the different locoregional anesthetic techniques used in ambulatory major traumatologic and orthopedic surgery, analyzing the advantages, inconveniences and complications, with a view to reducing their incidence. Regional techniques, particularly peripheral blocks and local anesthesia of the knee, are an excellent option in ambulatory major surgery. Among the neuroaxial techniques, epidural anesthesia offers results very similar to those of general anesthesia, and the intradural technique must be performed with low anesthetic doses. Control of perioperative fluid perfusion is a relevant factor in terms of the incidence of urinary retention (AU)

Análisis retrospectivo de la continencia urinaria en pacientes sometidos a braquiterapia post-resección transuretral prostática / Retrospective evaluation of urinary continence in patients submitted to brachytherapy after transurethral resection of the prostate gland

Introducción y objetivos: Algunos de los pacientes candidatos a la braquiterapia presentan historia previa de resección transuretral de la próstata (RTUP). La RTUP, sin embargo, crea una cavidad que puede llevar a algunas dificultades técnicas para la realización de braquiterapia. Tales condiciones tornan a la RTUP, previa a la braquiterapia, una contraindicación relativa a la realización de ésta. El objetivo del presente trabajo es evaluar las tasas de incontinencia urinaria en pacientes submetidos a braquiterapia después de una RTUP por medio de análisis retrospectiva. Materiales y métodos: En nuestro estudio analizamos 16 pacientes sometidos a RUTP previa a braquiterapia. Tras braquiterapia los pacientes fueron evaluados sobre síntomas del tracto urinario inferior a través del cuestionario ICS male SF. El intervalo de tiempo entre la RTUP y el tratamiento braquiterápico varió de 30 a 90 días, (media= 60 días). El seguimiento post braquiterapia varió entre 3 a 60 meses, (media= 30 meses). Resultados: Ninguno de los 16 pacientes evaluados presentó síntomas del tracto urinario inferior o incontinencia urinaria. Con el cuestionario ICS male SF la puntuación de interferencia en la calidad de vida obtuvo una media de 0,18 antes de la braquiterapia (variando de 0 a 1) y después de la braquiterapia de 0,20 (variando de 0 a 1) (p<0,001), donde las diferencias de los resultados no fue estadísticamente significativa. Algunas complicaciones fueron observadas como: disfunción eréctil, equimosis escrotal y retención urinaria. Los casos de disuria, equimosis escrotal y retención urinaria fueron de corta duración y resolución espontánea, éste último tras cateterismo vesical por 7 días. El paciente portador de disfunción eréctil presentó buena respuesta al uso semanal (3x/semana) de inhibidor de fosfodiesterasa tipo 5, después de un periodo de 6 meses. Conclusión: En concordancia con otros estudios, nosotros creemos que con alguna estrategia la RTUP no debería ser considerada una contraindicación relativa para la braquiterapia (AU)

Introduction and Objective: Some candidates for brachytherapy present with a previous history of prostate transurethral resection (TURP). Nonetheless, TURP generates a cavity that may lead to technical difficulties in performing brachytherapy. Such condition make a history of previous TURP a relative contra-indication for brachytherapy. The aim of this study is to evaluate the role of brachytherapy in urinary continence, in a group of patients with previous history of TURP. Materials and Methods: In our study, we analysed a group of 16 patients submitted to TURP pre-brachytherapy. The mean quality of life score from ICSmaleSF questionnaire ranged from 0 to 1 before and after brachytheraphy (average: 0,18 –before; average: 0,20 – after). There was no estatistically significant difference between the former values (p<0,001). After brachytherapy patients were evaluated for lower urinary tract symptoms. The time interval between TURP and brachytherapy ranged from 30 to 90 days (average: 60 days). Post-brachytherapy follow-up varied between 3 and 60 months (average: 30 months). Results: None of the 16 patients evaluated presented lower urinary tract symptoms nor urinary incontinence. Medical complications observed in patients were: dysuria, erectile dysfunction, scrotal ecchymosis and urinary retention . The cases of dysuria, scrotal ecchymosis and urinary retention observed were of short-duration, the last one with spontaneous resolution after 7 days of vesical catheterism. The patient presenting erectile dysfunction had a good response to oral type 5 fosfodiesteraseinhibitor three times a week, after a six month period. Conclusion: In accordance with other studies, we believe that with some strategy TURP should not be considered a relative contra-indication for brachytherapy (AU)

The effects of bilateral caudal epidural S2-4 neuromodulation on female sexual function.

This is a pilot study to evaluate the effects of caudal epidural S2-4 neuromodulation on female sexual function in a population of women with voiding dysfunction. We prospectively studied 36 consecutive female patients who underwent caudal epidural sacral neuromodulation. Patients received the Female Sexual Function Index (FSFI) questionnaire preoperatively and 6 months postoperatively. Six months after permanent implantation, the overall score on the FSFI improved by 52% (p = 0.05). Results were better in patients who underwent the treatment for voiding dysfunction compared to those who had pain as their primary complaint. In this group, the overall score improved by 157% (p = 0.004). Stimulation of S2-4 by bilateral caudal epidural neuromodulation in this small group of women with voiding dysfunction, retention, and/or pelvic pain resulted in self-reported improvements in sexual function. Further studies are needed to evaluate the potential role of S2-4 sacral stimulation in the treatment of female sexual dysfunction.

Urinary retention during sacral nerve stimulation for faecal incontinence: report of a case.

Sacral nerve stimulation (SNS) was proposed for the treatment of patients with urologic symptoms in 1967 but was not used until 1981. SNS has also proven to be a promising treatment in idiopathic faecal incontinence when conventional treatments have failed. The modality has been used for faecal incontinence since the mid-1990s. Eighty percent of the patients who were selected for percutaneous nerve evaluation (PNE) because of faecal incontinence report an improvement in the symptoms and qualify for a permanent implantation. Accordingly, SNS is now used for faecal incontinence and urologic symptoms. Reflex interactions between the bladder and the distal gastrointestinal tract are well known. The present case shows that SNS for faecal incontinence may significantly influence bladder function.
