RESUMO

ABSTRACT Objective To examine the impact of obesity on perioperative outcomes and urethral stricture recurrence after anterior urethroplasty. Material and Methods We reviewed our prospectively maintained single-surgeon database to identify men with anterior urethral strictures who had undergone anastomotic or augmentation urethroplasty between October 2012 and March 2018. In all, 210 patients were included for primary analysis of perioperative outcomes, while 193 patients with at least 12 months follow-up were included for secondary analysis of stricture recurrence. Patients grouped by BMI were compared using univariate and multivariate analyses for perioperative outcomes and log rank testing for recurrence-free survival. Results Overall, 41% (n=86) of patients were obese and 58.6% (n=123) had bulbar urethral strictures. Obese patients had significantly longer urethral strictures (mean=6.7cm±4.7) than nonobese patients (p <0.001). Though urethroplasty in obese patients was associated with increased estimated blood loss (EBL) relative to normal BMI patients on both univariate (p=0.003) and multivariate (p <0.001) analyses, there was no difference in operative time, length of stay, or complication rate between BMI groups. At a mean follow-up interval of 36.7 months, 15% (n=29) of patients had stricture recurrence, yet recurrence-free survival was not significantly different between groups (log rank p=0.299). Dorsal augmentation urethroplasty resulted in significantly fewer recurrences in obese patients compared to nonobese patients (p=0.036). Conclusion Despite the association with increased urethral stricture length and EBL, obesity is not predictive of adverse perioperative outcomes or stricture recurrence. Obese patients should be offered urethral reconstruction, but patient selection and preoperative counseling remain imperative.

RESUMO

SUMMARY INTRODUCTION Due to spongiofibrosis and inflammatory processes underlying the pathogenesis of urethral stricture, it is possible that the neutrophil-lymphocyte ratio (NLR) may give essential information about the course of the disease and recurrence possibilities. Our study aims to evaluate the correlation between NLR and recurrence rates. METHODS A total of 512 patients who underwent direct visual internal urethrotomy (DVIU) due to urethral stricture in our clinic between February 2010 and January 2018 were evaluated retrospectively. RESULTS The median follow up for non-recurrent and recurrent groups after DVIU was 30 and 36 months, respectively. During the follow-up, 280 (54.7%) of the patients had recurrences, and 232 (45,3%) had no recurrences. The mean time for recurrence after DVIU was 6,5±1,4 months, with a range of 1-36 months. The mean NLR in the non-recurrence group was 2,02±0,87, with a median of 1.9, and 3,66±2,30, with a median of 3 in the recurrence group. A highly significant statistical difference was observed between two groups in terms of neutrophil count and NLR (p: 0.000 - both). The area under curve value for NLR was 0.767, with a standard error of 0.021 (95% CI 0.727-0.808). The cut-off value of NLR was determined as 2.25, with a 70% sensitivity and 67,7% specificity. CONCLUSION By using NLR, the inflammatory features of the urethral tissue can be predicted, and possible recurrences after surgery can be estimated. Consequently, open urethroplasty techniques can be used in cases with a significant NLR value instead of the recurrent endoscopic procedure.


RESUMO INTRODUÇÃO Devido à espongiofibrose e processos inflamatórios subjacentes à patogênese da estenose uretral, pode-se pensar que a relação de linfócitos neutrofílicos (NLR) pode fornecer informações essenciais sobre o curso da doença e as possibilidades de recorrência. O objetivo do nosso estudo é avaliar a correlação entre NLR e taxas de recorrência. MÉTODOS Quinhentos e doze pacientes submetidos à uretrotomia interna visual direta (DVIU) devido à estenose uretral em nossa clínica entre as datas de fevereiro de 2010 e janeiro de 2018 foram avaliados retrospectivamente. RESULTADOS A mediana de acompanhamento para os grupos não recorrentes e recorrentes após a DVIU foi de 30 e 36 meses, respectivamente. Durante o seguimento, 280 (54,7%) dos pacientes tiveram recidivas e 232 (45,3%) não tiveram recidivas. O tempo médio de recorrência após a DVIU foi de 6,5±1,4 mês, com variação de 1-36 meses. A média da RNL no grupo sem recorrência foi de 2,02±0,87 com mediana de 1,9 e 3,66±2,30 com mediana de 3 no grupo com recidiva. Uma diferença estatística altamente significativa foi observada entre dois grupos em termos de contagem de neutrófilos e NLR (p: 0,000 - ambos). A área sob o valor da curva para NLR foi de 0,767 com um erro padrão de 0,021 (IC 95% 0,727-0,808). Valor de corte de NLR determinado como 2,25 com uma sensibilidade de 70%, especificidade de 67,7%. CONCLUSÃO Ao utilizar a RNL, as características inflamatórias do tecido uretral podem ser previstas e possíveis recidivas após a cirurgia podem ser estimadas. Dessa forma, técnicas de uretroplastia aberta podem ser usadas em casos com valor significativo de NLR em vez de procedimento endoscópico recorrente.

RESUMO

ABSTRACT Objectives To compare and assess various outcomes and success of buccal mucosal graft urethroplasty (BMGU) in patients with CKD versus patients having normal renal function. Material and Methods This was a retrospective, single centre study, during period 2013 to 2017. Patients were grouped into two groups. Group 1 had patients with estimated Glomerular Filtration Rate (eGFR)>60mL/min/1.73m2 while group 2 had patients with eGFR <60mL/min/1.73m2. eGFR was calculated according to the MDRD equation. The two groups were compared with regard to various outcomes like length, location of stricture, technique of graft placement, intra-operative blood loss (haemoglobin drop), duration of hospital stay, post-operative complications and recurrence. Results A total of 223 patients were included in study with group 1 had 130 patients and group 2 had 93 patients. Mean age of patients with CKD were higher (47.49 years versus 29.13 years). The mean follow-up period was comparable between both groups (23.29 months and 22.54 months respectively). Patients with CKD had more post-operative Clavien Grade 2 or higher complications (p=0.01) and a greater recurrence rates (p<0.001) than in non-CKD patients. On multivariate analysis, age and CKD status was significant predictor of urethroplasty success (p=0.004) (OR= 14.98 (1.952-114.94, 95% CI). Conclusions CKD patients are more prone to post-operative complications in terms of wound infection, graft uptake and graft failure and higher recurrence rates following BMGU.

RESUMO

Objetivos: La incidencia de lesión uretral bulboprostática secundaria a fractura pelviana es del 5-10%. Una uretroplastia exitosa garantiza el comienzo de la rehabilitación de los pacientes. Presentamos nuestra experiencia en el manejo quirúrgico de la estenosis uretral secundaria a fractura pelviana y resultados funcionales: tasa de éxito, reestenosis, disfunción eréctil e incontinencia urinaria. Evaluamos si existe asociación entre la falta de erecciones postrauma y la reestenosis. Materiales y métodos: Cincuenta y tres pacientes fueron operados durante el período comprendido entre 2001 y 2015. Todos fueron estudiados con cistoscopia flexible, cistouretrografía retrógrada y miccional. La técnica quirúrgica empleada fue la resección y anastomosis primaria. Se utilizó siempre la sistemática del abordaje perineal progresivo para lograr una anastomosis sin tensión. Interrogamos sobre la calidad de las erecciones posterior al trauma y después de la cirugía, y su estado de continencia urinaria. Se realizó un análisis estadístico donde se evaluó si la falta de erecciones era un factor de riesgo para recaída. Resultados: La edad promedio de los pacientes fue de 34,5 (r=17-67) años. La longitud promedio de la estenosis fue de 2,28 cm, siendo la uretra bulbomembranosa la más afectada (89%). La tasa de éxito fue del 86% (46/53), que asciende al 94% (50/53) al asociar un procedimiento endoscópico. Un solo paciente refirió disfunción eréctil postcirugía (1/19; 5,3%). Dos (3,7%) pacientes evolucionaron con incontinencia de orina de esfuerzo. No se hallaron diferencias estadísticamente significativas entre el grupo de pacientes con erecciones y aquellos sin erecciones en cuanto a la posibilidad de reestenosis. Conclusiones: La anastomosis bulbomembranosa por vía perineal es el tratamiento de elección de la estenosis uretral postfractura pelviana. Los índices de incontinencia de orina y disfunción eréctil no aumentan significativamente luego de la uretroplastia. En nuestra experiencia, la falta de erecciones preoperatoria no predice mayor índice de recaídas(AU)


Objectives: Bulboprostatic urethral stricture after pelvic fracture occurs in about 5-10%. A successful urethroplasty guarantees the beginning of patient recovery. We present our experience in the surgical management of posterior urethral stricture after pelvic fracture and functional outcomes (success and failure rates, erectile dysfunction and urinary incontinence). The association between the lack of erections post-trauma and the incidence of restenosis was also evaluated. Materials and methods: 53 patients were operated between 2001- 2015. Preop workout included a flexible cystoscopy and a combination of retrograde and voiding cystourethrogram to define the site and length of urethral stricture. Resection and primary anastomosis was the technique always employed. In all cases the progressive perineal approach was followed in order to achieve a tension free anastomosis. Erectile function and urinary continence were evaluated before and after surgery. Statistical analysis was performed to evaluate if lack of erections was a failure predictor. Results: Median age was 34.5 (r=17-67) years. Median urethral stricture length was 2.28 cm. Bulbomembranous junction was the most affected portion (89%). Success rate was 86% (46/53) ascending to 94% (50/53) when an endoscopic procedure was associated. One patient referred erectile dysfunction after surgery (1/19; 5.3%). Two patients (3.7%) developed stress urinary incontinence. The restenosis rate did not show statiscally differences between the erectile dysfunction and non-erectile dysfunction group. Conclusions: Perineal bulbomembranous anastomosis is the elected procedure for urethral stricture after pelvic fracture. Incidence of urinary incontinence and erectile dysfunction are not significantly elevated after urethroplasty. In our experience, lack of erections before surgery does not predict a higher rate of restenosis(AU)

RESUMO

ABSTRACT Purpose: Robotic assisted radical prostatectomy (RARP) presents challenges for the surgeon, especially during the initial learning curve. We aimed to evaluate early and mid-term functional outcomes and complications related to vesicourethral anastomosis (VUA), in patients who underwent RARP, during the initial experience in an academic hospital. We also assessed possible predictors of postoperative incontinence and compared these results with the literature. Materials and Methods: We prospectively collected data from consecutive patients that underwent RARP. Patients with at least 6 months of follow-up were included in the analysis for the following outcomes: time to complete VUA, continence and complications related to anastomosis. Nerve-sparing status, age, BMI, EBL, pathological tumor staging, and prostate size were evaluated as possible factors predicting early and midterm continence. Results were compared with current literature. Results: Data from 60 patients was assessed. Mean time to complete VUA was 34 minutes, and console time was 247 minutes. Continence in 6 months was 90%. Incidence of urinary leakage was 3.3%, no patients developed bladder neck contracture or postoperative urinary retention. On multivariate analysis, age and pathological staging was associated to 3-month continence status. Conclusion: Our data show that, during early experience with RARP in a public university hospital, it is possible to achieve good results regarding continence and other outcomes related to VUA. We also found that age and pathological staging was associated to early continence status.

RESUMO

ABSTRACT Objective To compare outcomes for single urethral cuff downsizing versus tandem cuff placement during artificial urinary sphincter (AUS) revision for urethral atrophy. Materials and Methods We identified 1778 AUS surgeries performed at our institution from 1990-2014. Of these, 406 were first AUS revisions, including 69 revisions for urethral atrophy. Multiple clinical and surgical variables were evaluated for potential association with device outcomes following revision, including surgical revision strategy (downsizing a single urethral cuff versus placing tandem urethral cuffs). Results Of the 69 revision surgeries for urethral atrophy at our institution, 56 (82%) were tandem cuff placements, 12 (18%) were single cuff downsizings and one was relocation of a single cuff. When comparing tandem cuff placements and single cuff downsizings, the cohorts were similar with regard to age (p=0.98), body-mass index (p=0.95), prior pelvic radiation exposure (p=0.73) and length of follow-up (p=0.12). Notably, there was no difference in 3-year overall device survival compared between single cuff and tandem cuff revisions (60% versus 76%, p=0.94). Likewise, no significant difference was identified for tandem cuff placement (ref. single cuff) when evaluating the risk of any tertiary surgery (HR 0.95, 95% CI 0.32-4.12, p=0.94) or urethral erosion/device infection following revision (HR 0.79, 95% CI 0.20-5.22, p=0.77). Conclusions There was no significant difference in overall device survival in patients undergoing single cuff downsizing or tandem cuff placement during AUS revision for urethral atrophy.

RESUMO

ABSTRACT Objectives To assess patient satisfaction and quality of life after urethroplasty using two different self-reported outcome measures and to compare it with objective clinical data. Materials and Methods We prospectively collected data from 35 consecutive patients who underwent urethroplasty from January 2013 to September 2014. Patient demographics, International Prostate Symptom Score (IPSS), quality of life score, urethral stricture surgery patient-reported outcome measure (USS-PROM), maximum flow rate (Qmax) and post-void residual urine were collected before, two and eight months after surgery. Failure occurred when any postoperative instrumentation was performed. General estimation equation was used to compare the results and linear regression analysis to correlate both questionnaires with objective data. Results Mean age was 61 years. Urethroplasties were equally divided between anastomotic and buccal mucosa grafts and 19 patients (59.3%) had a previous urethral procedure. Overall success rate was 87.5%. IPSS improved from a mean 19 at baseline to 5.32 at 8 months (p <0.001). The mean USS-PROM score also improved from 13.21 preoperatively to 3.36 after surgery (p <0.001) and 84.3% of patients were satisfied or very satisfied with surgical results. Mean Qmax increased from 4.64mL/s to 11mL/s (p <0.001). Strong negative correlation was found respectively between flow rate and USS-PROM (r=-0.531, p <0.001) and with IPSS (r=-0.512, p <0.001). Conclusions Significant improvements in urinary symptoms and in quality of life are expected after urethroplasty and they are correlated with objective measures.

RESUMO

ABSTRACT Purpose to assess the efficacy of transcorporal artificial urinary sphincter (AUS) implantation on continence for male stress urinary incontinence in cases of prior surgical treatment or/and radiation failure, and as a first option in radiation patients. Materials and Methods From March 2007 to August 2012, 37 male patients were treated with transcorporal AUS AMS™ 800. Twelve patients had primary placement of transcorporal cuff, a surgical option due to a previous history of radiation and 25 patients had secondary procedure after failure of AUS or urinary incontinence surgery. Functional urinary outcomes were assessed by daily pad use, 24-hour Pad-test and ICIQ-SF questionnaire. Quality of life and satisfaction were assessed based on I-QoL and PGI-I questionnaires. Results After a median of 32 months, the continence rate (0 to 1 pad) was 69.7%. Median pad test was 17.5g (0-159), mean ICIQ-SF score was 7.3/21 (±5.4) and mean I-QoL score was 93.9/110. A total of 88% of the patients reported satisfaction with the AUS. The 5-year actuarial revision-free for AUS total device was 51%. Patients for primary implant for radiation were not more likely to experience revision than non-radiation patients. Preservation of erections was reported in half of the potent patients. Conclusions Transcorporal AUS cuff placement is a useful alternative procedure option for severe male UI treatment, especially in patients with a compromised urethra after prior surgery or radiation. A high continence rate was reported and implantation as first option in radiation patients should be considered.

RESUMO

ABSTRACT Aim: To evaluate the long term outcomes of temporary urethral stent placement for the treatment of recurrent bulbar urethral stricture. Materials and Methods: Twenty-eight patients who underwent temporary polymer coated urethral stent placement due to recurrent bulbar urethral stricture between 2010 and 2014 were enrolled in the study. The long term outcomes of the patients were analyzed. Results: The mean age of the patients was 62.3±6.4 (44–81). The overall clinical success was achieved in 18 (64.2%) of the 28 patients at a median (range) follow-up of 29 (7–46) months. No patient reported discomfort at the stent site. Stone formation was observed at the urethral stent implantation area only in one patient. Stenosis occurred in the distal end of the stents in two patients and took place in bulbar urethra in seven patients after removed the stents. The mean maximum urine flow rates were 6.24±2.81mL/sec and 19.12±4.31mL/sec before and at 3 months after the procedure, respectively. Conclusion: In this study, the success rate of temporary urethral stent placement has remained at 64.2% at a median follow-up of 29 months. Therefore, our outcomes have not achieved desired success rate for the standard treatment of recurrent bulbar urethral stricture.

RESUMO

ABSTRACT Purpose: To demonstrate the effect of total reconstruction technique on postoperative urinary continence after laparoscopic radical prostatectomy (LRP). Material and Methods: LRP was performed using a standard urethrovesical anastomosis in 79 consecutive patients (Group-A) from June 2011 to October 2012, and a total reconstruction procedure in 82 consecutive patients (Group-B) from June 2012 to June 2013. The primary outcome measurement was urinary continence assessed at 1, 2, 4, 12, 24 and 52 weeks after catheter removal. Other data recorded were patient age, body mass index, International Prostate Symptoms Score, prostate volume, preoperative PSA, Gleason score, neurovascular bundle preservation, operation time, estimated blood loss, complications and pathology results. Results: In Group-A, the continence rates at 1, 2, 4, 12, 24 and 52 weeks were 7.59%, 20.25%, 37.97%, 58.22%, 81.01% and 89.87% respectively. In Group-B, the continence rates were 13.41%, 32.92%, 65.85%, 81.71%, 90.24% and 95.12% respectively. Group––B had significantly higher continence rates at 4 and 12 weeks after surgery (P<0.001 and P=0.001). There were no significant differences between the groups with respect to patient's age, body mass index, prostate-specific antigen level, prostate volume, IPSS, estimated blood loss, number of nerve-sparing procedures and postoperative complications. Conclusions: Total reconstruction technique in the procedure of urethrovesical anastomosis during LRP improved early recovery of continence.

RESUMO

ABSTRACTPurpose:

To evaluate continence after radical prostatectomy in prostate cancer patients, in whom a new method of the bladder neck reconstruction (BNR) using deep dorsal stitch was implemented (deep single stitch through all bladder layers directly dorsal to the bladder opening after “tennis racket” reconstruction) and to provide justification for its use by means of anatomical study in cadavers.

Material and Methods:

Open radical retropubic prostatectomy was performed in 84 patients: 39 patients with a new BNR method used to improve continence and control group of 45 patients with standard “tennis racket” BNR. Median follow-up was 14 months in control group and 12 months in study group. Continence recovery was accessed early postoperatively and every 3 months thereafter. Anatomical study was performed on 2 male fresh cadavers reproducing two different BNR techniques to clarify any underlying continence related mechanisms.

Results:

Patients with new BNR achieved full continence significantly faster (p=0.041), but the continence rates after 12 months were similar between groups. The severity of incontinence up to month 9 was significantly reduced in BNR group. The anastomotic stricture rate was not affected. Applying new BNR to the cadaver model revealed effects on early continence, namely presence of proximal passive closure mechanism in area of bladder neck.

Conclusions:

Continence in patients with the new BNR method using deep dorsal stitch recovered significantly faster. Moreover, a reduced grade of residual incontinence was documented. The effect was non-significant at month 12 of follow-up, meaning that only early effect was present.

RESUMO

Objective To review the technique and outcome of perineal urethrostomy or urethral perineostomy and to identify factors related to the procedure failure. Material and methods We studied 17 patients who underwent perineal urethrostomy between 2009-2013 in a single hospital. Success was defined as no need for additional surgical treatment or urethral dilatation. We reviewed the clinical data related to age, weight, previous urethral surgery, diabetes, hypertension, ischemic cardiopathy, lichen sclerosus and other causes and studied their association with the procedure failure (univariate analysis). We completed the analysis with a multivariate test based on binary regression. Results The average follow-up was 39.41 months. From all the causes, we found Lichen Sclerosus in 35%, idiopathic etiology in 29% and prior hypospadia repair in 18%. Postoperative failure occurred in 3 patients, with a final success of 82.4%. The binary regression model showed as independent risk factors ischemic cardiopathy (OR: 2.34), and the presence of Lichen Sclerosis (OR: 3.21). Conclusions The success rate with the perineal urethrostomy technique shows it to be a valid option above all when we preserve the urethral blood supply and plate.

RESUMO

Purpose Endoscopic urethrotomy is an alternative method in treatment of urethral stricture. However, it have high recurrence rate because of the remained fibrotic tissue. Removal of the fibrotic tissue can maintain the patency of the urethral lumen after the procedure. We report the therapeutic efficacy of our initial experience using pediatric resectoscope for treating anterior urethral stricture in 16 cases. Materials and Methods From January 2009 to April 2011, transurethral resection with pediatric resectoscope was primarily performed on 16 patients with anterior urethral stricture. Retrograde urethrography, uroflowmetry, postvoid residual volume, IPSS score and QoL score were performed preoperatively. We used 11.5Fr pediatric resectoscope (Wolf) and monopolar electrosurgical generator. The stricture was incised under vision at the 12 o'clock location or the site of maximum scar tissue or narrowing in asymmetric strictures for working space. After incision, transurethral resection with pediatric resectoscope was performed to all scar tissues. Monopolar cutting current was set on 45 watt and coagulation current was set on 30 watt, fulgurate mode. Postoperatively, drainage of the bladder was performed for 7 days using an 18F latex catheter. Patients were followed up by IPSS score, QoL score, uroflowmetry and postvoid residual volume. Results Successful results without recurrence were achieved in 11 of 16patients. Postoperative urethral dilation had been performed average 2.4 times (0∼6 times). When we classified the results by etiology, the number of successful results in strictures with a trauma, iatrogenic, or unknown cause was 5 (7/11), 3 (3/4) and 1 (1/1), respectively. In 5 patients who failed treatment, we repeated transurethral resection with pediatric resectoscope in 1 patient, and periodic urethral dilation in 4 patients. No operative complications occurred in any patients. Conclusions Transurethral resection with ...

RESUMO

PURPOSE: To analyze the influence of urethral mobility and Valsalva leak point pressure on postoperative outcomes of transobturator sling (TOT) for female stress urinary incontinence. MATERIALS AND METHODS: A prospective cohort was conducted including 66 patients submitted to TOT from March 2006 to May 2009. Urethral hypermobility was defined as mobility ≥ 30º on Q-tip test, and Valsalva leak point pressure (VLPP) was classified as greater than 60 cmH2O or 60 and less on preoperative urodynamics. These parameters were compared through well defined postoperative objective and subjective success criteria. Intensity of urinary leakage and quality of life was analysed by ICIQ-SF. Statistical analysis was accomplished and the results rendered significant if p < 0.05. RESULTS: Mean follow up was 10 months (3 to 28). Mean age was 55 years (33 to 80), 70% were white and 30% African descendent, mean body mass index was 27 (21 to 38), average vaginal and abdominal deliveries were 2.8 and 0.5 respectively. A quarter had prior stress incontinence surgery. Patients with urethral hypermobility had higher objective success rates (98% versus 81.25%, p = 0.04). The subjective success rate was also greater in the hypermobility group (84% versus 62.5%), but statistical significance was not reached (p = 0.07). VLPP had no influence on either objective or subjective postoperative success rates (p = 0.17 and 0.34, respectively). In the subgroup analysis, those with low mobility and high VLPP had worse objective success rates in comparison to the group with hypermobility and low VLPP (p = 0.04) and also in relation to the remaining of the studied population. Other possible prognostic factors (previous surgery, mixed incontinence, gestational status) had no influence on success rates. CONCLUSIONS: High urethral mobility, regardless of the sphincteric status indicated by VLPP, is a favorable prognostic factor for tension-free transobturator tape procedure. No relationship was demonstrated between postoperative success rates and VLPP.

RESUMO

PURPOSE: V-LocTM180 (Covidien Healthcare, Mansfield, MA) is a new unidirectional barbed suture that may reduce loss of tension during a running closure. We evaluated the use of the barbed suture for urethrovesical anastomosis (UVA) during robotic assisted laparoscopic prostatectomy (RALP). Time to completion of UVA, post-operative anastomotic leak rate, and urinary incontinence were compared in patients undergoing UVA with 3-0 unidirectional-barbed suture vs. 3-0 MonocrylTM (Ethicon, Somerville, NJ). MATERIALS AND METHODS: Data were prospectively collected for 70 consecutive patients undergoing RALP for prostate cancer between November 2009 and October 2010. In the first 35 patients, the UVA was performed using a modified running van Velthoven anastomosis technique using two separate 3-0 monofilament sutures. In the subsequent 35 patients, the UVA was performed using two running novel unidirectional barbed sutures. At 7-12 days postoperatively, all patients were evaluated with a cystogram to determine anastomotic integrity. Urinary incontinence was assessed at two months and five months by total daily pad usage. Clinical symptoms suggestive of bladder neck contracture were elicited. RESULTS: Age, PSA, Gleason score, prostate size, estimated blood loss, body mass index, and clinical and pathologic stage between the 2 groups were similar. Comparing the monofilament group and V-LocTM180 cohorts, average time to complete the anastomosis was similar (27.4 vs. 26.4 minutes, p = 0.73) as was the rate of urinary extravasation on cystogram (5.7 % vs. 8.6%, p = 0.65). There were no symptomatic bladder neck contractures noted at 5 months of follow-up. At 2 months, the percentage of patients using 2 or more pads per day was lower in the V-LocTM180 cohort (24% vs. 44%, p < 0.02). At 5 months, this difference was no longer evident. CONCLUSIONS: Time to complete the UVA was similar in the intervention and control groups. Rates of urine leak were also comparable. While the V-LocTM180 was associated with improved early continence, this difference was transient.

RESUMO

PURPOSE: Tape tension adjustment is an essential procedure in mid-urethral sling surgery. The goal of this study was to determine if intraoperative maximal urethral closing pressure (MUCP) elevation could be used as a reference value for adequate tape tension adjustment and predict transobturator (TOT) sling surgery outcome. MATERIALS AND METHODS: A prospective study was performed using MUCP measurements just before tape insertion and just after tension adjustment during surgery. Clinical data including preoperative urodynamic results were collected. The cure rate was determined by questionnaire. Patients were divided into two groups. The MUCP elevation group included patients with a MUCP elevation of more than 10 cmH2O before tape insertion; the others were regarded as the non-elevation group. The cure rate and pre- and postoperative clinical variables were compared between the two groups. RESULTS: A total of 48 patients had TOT surgery. The MUCP elevation group (n=19) and the non-elevation group (n=29) were similar with regard to patient characteristics and the preoperative parameters including age, mixed incontinence prevalence, Q-tip angle, peak flow rate, MUCP and the valsalva leak point pressure (VLPP). The mean follow-up period was nine months. The cure rate was significantly higher in the group with MUCP elevation than in the non-elevation group (84 percent vs. 52 percent, p=0.02). There was no significant difference in the mean postoperative peak flow rate between the two groups and there was no retention episode. CONCLUSIONS: MUCP elevation of more than 10 cmH2O just after tape insertion was a prognostic factor.

RESUMO

PURPOSE: Pelvic fracture urethral distraction defect is usually managed by the end to end anastomotic urethroplasty. Surgical repair of those patients with post-traumatic complex posterior urethral defects, who have undergone failed previous surgical treatments, remains one of the most challenging problems in urology. Appendix urinary diversion could be used in such cases. However, the appendix tissue is not always usable. We report our experience on management of patients with long urethral defect with history of one or more failed urethroplasties by Monti channel urinary diversion. MATERIALS AND METHODS: From 2001 to 2007, we evaluated data from 8 male patients aged 28 to 76 years (mean age 42.5) in whom the Monti technique was performed. All cases had history of posterior urethral defect with one or more failed procedures for urethral reconstruction including urethroplasty. A 2 to 2.5 cm segment of ileum, which had a suitable blood supply, was cut. After the re-anastomosis of the ileum, we closed the opened ileum transversely surrounding a 14-16 Fr urethral catheter using running Vicryl sutures. The newly built tube was used as an appendix during diversion. RESULTS: All patients performed catheterization through the conduit without difficulty and stomal stenosis. Mild stomal incontinence occurred in one patient in the supine position who became continent after adjustment of the catheterization intervals. There was no dehiscence, necrosis or perforation of the tube. CONCLUSION: Based on our data, Monti's procedure seems to be a valuable technique in patients with very long complicated urethral defect who cannot be managed with routine urethroplastic techniques.

RESUMO

Introduction: Posterior urethral strictures after prostatic radiotherapy or surgery for benign prostatic hyperplasia (BPH) refractory to minimal invasive procedures (dilation and/or endoscopic urethrotomy) are challenging to treat. Published reports of alternative curative management are extremely rare. This is a preliminary report on the treatment of these difficult strictures by urethroplasty. Materials and Methods: Seven cases were treated: 4 cases occurred after open prostatectomy or transurethral resection of the prostate for BPH, one case after external beam irradiation and 2 after brachytherapy. The 4 cases after BPH-related surgery were in fact complete obstructions at the bladder neck and the membranous urethra with the prostatic urethra still partially patent. Anastomotic repair by perineal route was done in all cases with bladder neck incision in the BPH-cases and prostatic apex resection in the radiotherapy cases. Results: Mean follow-up was 31 months (range: 12-72 months). The operation was successful, with preserved continence, in 3 of the 4 BPH-cases and in 2 of the 3 radiotherapy cases. An endoscopic incision was able to treat a short re-stricture in the BPH-patient and a longer stricture at the bulbar urethra could be managed with a perineostomy in the radiotherapy-patient. Conclusion: Posterior non-traumatic strictures refractory to minimal invasive procedures (dilation/endoscopic urethrotomy) can be treated by urethroplasty using an anastomotic repair with a bladder neck incision if necessary.

RESUMO

OBJECTIVE: To prospectively evaluate the outcome of using a two-suture technique for the vesicourethral anastomosis (VUA) during radical retropubic prostatectomy (RRP). MATERIAL AND METHODS: Two groups of 50 patients each underwent nerve-sparing RRP for localized prostate cancer by one surgeon. In one group, the vesicourethral anastomosis was performed using 2 Vicryl 2-0 stitches placed at the 3- and 9-o'clock positions and in the other group 6 Vicryl 2-0 stitches were placed at the 2-, 4-, 6-, 8-, 10- and 12-o'clock positions. The intraoperative and perioperative parameters analyzed were time to perform the VUA, time to remove the drain and hospitalization. The rate of incontinence, anastomotic stricture and erectile function were included in the outcome analysis. RESULTS: The anastomotic time differed statistically between the 2 groups (mean 3.3 minutes for the 2-suture group and 10.5 minutes for the 6-suture group, p < 0.0001) with similar periods of drain removal (mean 3.12 days for the 2-suture group and 3.45 days for the 6-suture group; p = 0.13) and hospitalization (mean 4.66 days for the 2-suture group and 5.3 days for the 6-suture group; p = 0.09). The functional outcome was excellent for the 2-suture group with no patient suffering from incontinence or anastomotic strictures 1 year postoperatively, while in the 6-suture group there were 2 patients (4 percent) suffering from incontinence (2 underwent sling procedure) and 1 patient suffered from anastomotic stricture. CONCLUSION: The low number of sutures in the 2-suture VUA technique reduces operating times, does not influence perioperative and intraoperative parameters and results in excellent functional outcome.

RESUMO

OBJECTIVES: To evaluate the impact of surgical treatment of stress urinary incontinence on the sexual function of women and to identify whether such treatment can improve their sexual function and overall quality of life. MATERIALS AND METHODS: 64 heterosexual women with such indication were studied using the Female Sexual Function Index (FSFI) questionnaire, modified by introducing one question to evaluate the impact of urine loss. This was applied preoperatively and six months after surgery. RESULT: Among these 64 patients, 60.94 percent had regular sexual activity, while 39.06 percent did not. Among sexually active patients, 59 percent had urine loss during sexual intercourse and, of these, 87 percent had urine losses in half or more of sexual relations. There were no statistically significant differences in assessments of desire, arousal, lubrication, orgasm, satisfaction and pain, or in totaling the scores, between the preoperative period and six months after surgical treatment. However, the scores for urine losses during sexual intercourse were significantly better after the operation. CONCLUSIONS: Analysis of the results allowed the following conclusions to be reached: Urine lost during sexual activity was frequent among patients with stress urinary incontinence. Suburethral support surgery did not jeopardize sexual activity. Patients cured of stress urinary incontinence did not present improvement in sexual function.
