Can Neoadjuvant Chemotherapy Cause Postoperative Hydronephrosis After Radical Cystectomy?

OBJECTIVE: This study's objective is to assess the effect of preoperative factors on postoperative hydroureteronephrosis (HUN) after radical cystectomy (RC) in patients with bladder cancer (BC). METHODOLOGY: Patients who underwent RC for BC between January 2019 and November 2022 and had unilateral or bilateral postoperative HUN were retrospectively analyzed. Patients without preoperative HUN but with postoperative HUN constituted the patient group, while patients without both preoperative and postoperative HUN constituted the control group, and they were compared with each other. RESULTS: Neoadjuvant chemotherapy (NAC) and postoperative metastasis were positively correlated with postoperative HUN (r = 0.238, P = 0.007, and r = 0.203, P = 0.021, respectively). Multivariate logistic regression analysis showed that the postoperative HUN was significantly associated with NAC (P = 0.048; Exp(B) = 6.896, 95% confidence interval [CI] 1.02-46.9) but not associated with the presence of metastasis (P = 0.054). Moreover, NAC increased the possibility of undergoing revision surgery (P = 0.002; Exp(B) = 26.9, 95% CI 3.2-225). CONCLUSIONS: NAC is an independent factor for impaired anastomotic healing, increased postoperative HUN, and the need for revision surgery in patients with BC.

Confirmation of PSMA expression measured on [68Ga]Ga-PSMA PET/CT by immunohistochemistry in prostate adenocarcinoma.

BACKGROUND: Our aim is to determine the accuracy of [68Ga]Ga-PSMA PET/CT in showing PSMA expression in primary prostate cancer and to investigate the relationship between SUVmax and immunohistochemical PSMA expression, Gleason score, and PSA value. MATERIAL AND METHODS: We retrospectively analyzed 66 male patients who were diagnosed with primary prostate adenocarcinoma, underwent pre-treatment [68Ga]Ga-PSMA PET/CT examination for staging, and performed radical prostatectomy between March 2018-August 2020. Immunohistochemical staining was applied to the radical prostatectomy specimens of all patients to detect PSMA expression. The results were evaluated as an immunoreactive score (IRS) and a modified IRS was obtained. Gleason score groups and prostate-specific antigen (PSA) serum values of the patients were obtained from the patient files. RESULTS: The high SUVmax of primary prostate tumors was significantly correlated with a high modified IRS score (score 2; 3), high PSA value, high Gleason score, and metastasis. In correlation analysis, a positive correlation was found between SUVmax and PSA value and modified IRS score (r = 0.69, p = 0.001; r = 0.39, p = 0.001). In addition, there was a statistically significant weak correlation between PSA serum concentration and modified IRS scores (r = 0.267; p = 0.03). In regression analysis, the percentage of positive cells had a statistically significant and increasing effect on SUVmax (p = 0.031; std beta = 0.268; 95% CI = 0.231-4.596). CONCLUSIONS: In prostate adenocarcinoma, SUVmax of the primary tumor in [68Ga]Ga-PSMA PET/CT correlates with immunohistochemical PSMA expression. In addition, high SUVmax is associated with markers of poor prognoses, such as high PSMA expression, PSA value, and Gleason score.

Efficacy of perineal electrical stimulation in men with urinary incontinence after radical prostatectomy. A prospective randomized controlled trial.

OBJECTIVE: To evaluate the efficacy of perineal electrical stimulation (ES) on anxiety, depression, incontinence-related quality of life (QoL), and clinical parameters in men with urinary incontinence (UI) after radical prostatectomy (RP). METHODS: Fifty-eight men with UI after RP were randomized into two groups using the random numbers generator as follows: Group 1 received perineal ES (n:29), and Group 2 no treatment (n:29). Perineal ES was performed in lithotomy position via a stimulation device (Enraf Myomed 632) with surface electrodes, 3 days a week, 20 min a day, for a total of 24 sessions for 8 weeks. Men were evaluated in terms of continence rates (primary outcome), incontinence severity (24 h-pad test), incontinence episodes (3-day bladder diary), anxiety-depression (HADS), QoL (IIQ-7), and improvement rates and treatment satisfaction (Likert scale) at the baseline and the end of treatment (8th week). RESULTS: A statistically significant improvement was found in all parameters except depression in Group 1, in the severity of incontinence and QoL parameters in Group 2 at the 8th week compared to the baseline values (p < 0.05). At the end of treatment; the severity of incontinence, incontinence episodes, QoL, and anxiety were significantly improved in Group 1 compared to Group 2 (p < 0.05). No difference was found between the two groups in terms of depression (p > 0.05). The continence and improvement rates and treatment satisfaction were significantly higher in Group 1 than in Group 2 (p < 0.05). CONCLUSION: Perineal ES is more effective than no treatment in men with UI after RP as an alternative ES option that is well tolerated and does not produce serious adverse events. Clinical Trial Registration: This study was registered with ClinicalTrials.gov number, NCT05236140.

The Impact of COVID-19 Pandemic on Urological Emergencies, 8 Months Results of a Multicenter Retrospective Study From Turkey.

Objectives: We aimed to reveal the change of urological emergencies during the COVID-19 pandemic compared to the same period of the previous year. Methods: The number of admissions to the emergency department (ED), admissions to the urology outpatient clinic, emergency urological consultations, and urological and emergency urological surgeries during the periods April-November-2019 and April-November-2020 were recorded. The data of the COVID-19 period were compared with the previous year. Results: While the number of admissions to the urological outpatient clinic was 160,447 during the COVID period, it was 351,809 during the non-COVID period. The number of admissions to the ED decreased from 3.2 million to 2.4. The number of admissions to the urology outpatient clinic significantly decreased by 54% during the pandemic (p=0.001). Percutaneous cystostomy performed due to acute urinary obstruction decreased by 27.96%, double J stent, nephrostomy decreased by 16.61%, and ureterorenoscopy decreased by 12.26%. Urogenital trauma also decreased. On the contrary, surgical procedures performed due to penile fracture, gross hematuria, Fournier gangrene, and testicular torsion increased. Conclusion: During the COVID-19 pandemic, a significant decrease was observed in non-COVID patients' admissions to the emergency and urology department, and in urologic surgeries.

A short course of antimicrobial therapy for asymptomatic bacteriuria is safe and effective before urologic procedures.

INTRODUCTION: In the presence of asymptomatic bacteriuria (ASB) before the urological procedure, the duration of antimicrobial treatment is controversial. This study aims to evaluate whether a short course of antimicrobial therapy is safe and effective in cases with ASB before urological procedures. METHODOLOGY: We retrospectively reviewed adult patients who had ASB before undergoing several urological procedures between 2011 and 2019. The patients received a single dose of an appropriate parenteral antibiotic, determined by antimicrobial sensitivity testing, 30 to 60 minutes before the urological procedure. If a urinary catheter was placed post-procedure, a second dose was given. RESULTS: A total of 293 patients who had ASB before undergoing several urological procedures were included in the study. The total number of procedures was 328. Female/male ratio was 92 (31.4%)/201 (68.6%). The mean age was 63.7 ± 14.9 years. The most common isolated microorganisms were Escherichia coli (155 [47%]), Klebsiella pneumoniae (38 [11.6%]), and Pseudomonas aeruginosa (28 [8.5%]). The most common antimicrobial used was ertapenem. A second dose antimicrobial was given for 290 procedures due to a urinary catheter after a urological procedure. The mean hospitalization time was 3.97 ± 3.42 days. None of the patients developed infectious complications. CONCLUSIONS: This study has demonstrated that a single dose of parenteral antimicrobial drug administered 30-60 minutes before the urologic procedures and a second dose in the presence of a post-procedure catheter, was adequate to prevent post-procedure septicemia and urinary tract infection.

VI-RADS score and tumor contact length in MRI: A potential method for the detection of muscle invasion in bladder cancer.

BACKGROUND: Vesical Imaging Reporting and Data System (VI-RADS) is a useful tool for evaluating muscle layer invasion of bladder cancer (BCa) on magnetic resonance imaging (MRI). PURPOSE: To evaluate the diagnostic performance of bladder MRI to detect the muscle layer invasion of BCa using VI-RADS score and quantitative MRI parameters. METHODS: Preoperative bladder MRI was performed in 73 BCa patients. Two observers independently evaluated the MR blinded to histopathological data and classified the tumors according to VI-RADS criteria. Moreover, the quantitative parameters (maximum tumor diameter; Dmax, tumor contact length; TCL, and tumor apparent diffusion coefficient; ADC values) were independently measured by observers. The diagnostic performance of the VI-RADS score and quantitative values were evaluated by using receiver operating characteristic (ROC) analysis. Interobserver agreement was evaluated using the weighted-kappa coefficient (κ). RESULTS: For the VI-RADS score, the AUC (area under the curve) was 0.968 and accuracy was 90.4% for Observer 1, and AUC was 0.953, accuracy was 89% for Observer 2. The AUC of TCL, TCL/DMax, and ADC values was 0.918, 0.675, and 0.832. In patients with a VI-RADS score ≥ 3, when a threshold value of TCL > 19.5 mm is used as complementary to the VI-RADS score, the accuracy of MRI for Observer-1 increases 100% and 97.26% for Observer-2. There was a good-excellent agreement between the observers in assessing the VI-RADS scores and quantitative parameters. CONCLUSION: Evaluation of bladder MRI using both VI-RADS criteria and TCL is successful and highly reproducible for detecting muscle layer invasion in patients with BCa.

Comparison of 68Ga-PSMA-I/T PET-CT and Multiparametric MRI for Locoregional Staging of Prostate Cancer Patients: A Pilot Study.

BACKGROUND/AIM: The objective of this work was to assess the value of 68Ga-DOTAGA-(3-iodo-y)fk(Sub-KuE) positron emission tomography (68Ga-PSMA-I/T PET-CT) and multiparametric magnetic resonance imaging (mp-MRI) for preoperative staging in prostate cancer (PCa) patients who underwent radical prostatectomy (RP) by validating with postoperative histopathology data. MATERIALS AND METHODS: We prospectively investigated 30 consecutive PCa patients who had both mp-MRI and 68Ga-PSMA-I/T PET-CT before laparoscopic RP. The seminal vesicle invasion (SVI), lymph node metastasis (LNM), bladder neck invasion (BNI), and extracapsular extension (ECE) were investigated separately. The diagnostic performances of mp-MRI and 68Ga-PSMA-I/T PET-CT were assessed using histopathological results. RESULTS: Both mp-MRI and 68Ga-PSMA-I/T PET-CT were not statistically significant in the evaluation of SVI, BNI, and ECE preoperatively but had statistically significant results in the assessment of LNM. mp-MRI had higher overall sensitivity for ECE, overall specificity for SVI, ECE, and BNI, and positive predictive value for ECE, SVI, BNI. 68Ga-PSMA-I/T PET-CT had higher overall sensitivity for BNI, and negative predictive value for BNI and LNM. CONCLUSION: mp-MRI has superior specificity, sensitivity, and accuracy for assessing ECE and SVI. Both imaging modalities had similar specificity, sensitivity, and accuracy for determining BNI. However, both imaging modalities had low diagnostic accuracy for LNM on histopathology.

Do seasonal variations in ambient temperature, humidity and daylight duration affect semen parameters? A retrospective analysis over eight years.

We aimed to evaluate the possible effects of seasonal variation on semen parameters. We retrospectively analysed the data of 6,116 semen samples collected at a university hospital for eight years. The past ambient temperature, relative humidity and daylight duration records, and birth registry of the province were obtained to examine the relationship of seasonal changes in semen parameters with annual birth rates and environmental factors. The mean age was 33.03 ± 6.86 years. We found a significant difference between months for sperm concentration (p < .0001), total sperm count (p < .0001), progressively motile sperm count (p < .0001) and normal sperm morphology (p = .028). The sperm concentration and total count were significantly lower in July and August compared with December, May and June. The progressively motile sperm count in October was 23.6% less than the value of May. The temperature and temperature-humidity index were negatively correlated with semen parameters. The highest number of births was in the summer. However, no correlation was present between deliveries and the semen concentration regarding months (rs  = 0.199, p = .083). In conclusion, we observed significant seasonal and monthly differences in sperm concentration, sperm count and progressively motile sperm count. Increased ambient temperature due to seasonal changes may be a detrimental factor for semen parameters.

Which patient should start empirical antibiotic treatment in urinary tract infection in emergency departments?

OBJECTIVES: This study aims to determine the factors that would lead the doctors in EDs to a more the accurate diagnosis of urinary tract infection (UTI) and the correct initiation of empirical antibiotherapy in the emergency room and reduce the use of unnecessary antibiotherapy. METHODS: This study is a prospective observational study from a single-center, investigating patients with an age of 18 years and older who presented to the emergency department (ED) with the symptoms of UTI between January and May 2018. The guiding parameters to establish a UTI diagnosis and start an empirical antibiotherapy were investigated between the negative (Group 1) and positive (>103 colonies) (Group 2) groups, as a result of urine culture in terms of urine culture. RESULTS: Our study included a total of 108 patients (59 women and 49 men). The average age was 47.11 ± 14.97. Age and gender were similar among the groups and not a discriminating factor in the diagnosis of UTI. High Charlson Comorbidity Index score, history of chronic kidney failure and cerebrovascular disease, leukocyte esterase, nitrite positivity, and leukocyte cluster presence were higher in Group 2. We suggest that these parameters might be predictive values to detect bacterial growth in urine culture. Empirical antibiotherapy was started in 48.4% of the patients in Group 1 and 95.7% of the patients in Group 2. CONCLUSIONS: In EDs, admission complaints of the patients and physical examination findings do not always result in the diagnosis of UTI. Our study showed that UTI diagnosis could be made more accurately using leukocyte esterase, nitrite positivity, the presence of leukocyte clusters, and the Charlson Comorbidity Index score. We also suggest that regional antibiotic resistance should be considered before starting empirical antibiotherapy.

Is There a Correlation Between Behçet Disease and Lower Urinary Tract Symptoms?

PURPOSE: In this study, we aimed to determine the prevalence of lower urinary tract symptoms (LUTS) in patients with Behçet disease (BD) and to investigate the relationship between the severity of BD and LUTS. METHODS: Fifty-five patients with BD were included in this study from January to December 2018. All patients received a detailed urological evaluation. Additionally, BD activity was investigated using the Behçet Disease Current Activation Form. The International Prostate Symptom Score (IPSS), International Consultation on Incontinence Questionnaire Short Form, 8-item overactive bladder questionnaire forms, uroflowmetry, and postvoid residual urine volume were evaluated. RESULTS: The mean age of the patients was 42.6 years. The mean activity score of BD was 4.6±3.2 and the mean IPSS score was 7.3±7.3. Sex had no significant effect on the BD activity score. The BD activity score was significantly correlated with the IPSS score, frequency of daytime urination, nocturia, and urgency. It was also correlated with the presence and the severity of urinary incontinence and the effect of urinary incontinence on daily life. Peak flow rate, voided volume, and the postvoid residual urine volume were not correlated with the BD activity score. CONCLUSION: LUTS were highly prevalent in patients with BD, and the severity and current activity of BD were correlated with frequency, nocturia, urgency, and urinary incontinence. Therefore, a urological evaluation of patients with BD in whom the activity and severity of the disease is elevated should be carried out comprehensively and patients should be managed accordingly.

Female buccal mucosa graft urethroplasty: a new modified ventral onlay "AZ" technique.

INTRODUCTION AND HYPOTHESIS: To present the surgical details and the outcomes of our modified ventral onlay buccal mucosal graft (BMG) urethroplasty technique in female patients with urethral strictures. METHODS: We included the first seven female patients who had BMG urethroplasty between January 2015 and April 2019 and had at least 6 months of follow-up. Patient age, stricture length, comorbidities, number of previous treatments, pre- and postoperative uroflowmetry data, and post-void residual volumes were recorded. RESULTS: The mean patient age was 56.7 (44-80) years. The mean stricture length was 3.1 (2-4) cm. The mean postoperative follow-up time was 23 (7-48) months. The preoperative mean maximal flow rate (Qmax) was 5.1 (3.2-9.5) ml/s and post-void residual urine volume (PVR) was 84.4 (37-158) ml. At the 3rd month after surgery, mean Qmax was 31.8 (24.7-36.2) ml/s, and PVR volume was 7.1 (0-16) ml. Three patients had the postoperative 2-year follow-up, and 12th and 24th month mean Qmax values were 28 (23.6-33.2) ml/s and 28.5 (24.1-31.1) ml/s, respectively. The mean operation time was 63.8 (55-113) min. We did not observe any infection, vaginal erosion, urinary incontinence, or oral discomfort due to graft harvesting postoperatively. CONCLUSION: Female urethroplasty provides high cure rates and should be performed in case of recurrent FUS. The early and medium-term results of our modified new technique indicated that it might be used as a simple alternative to current techniques. In all of our patients, it significantly increased the flow rate and reduced PVR without any significant complications.

Prostate cancer incidence and diagnosis in men with PSA levels >20 ng/ml: is it possible to decrease the number of biopsy cores?

OBJECTIVES: To define if less number of cores would be sufficient to diagnose prostate cancer (PCa) in men with PSA levels >20 ng/ml and to reveal the cancer detection rates in this population. METHODS: The data of the men who had 12-core prostate biopsy with a PSA value >20 ng/mg were reviewed. We recorded age, prostate volume, PSA level, and pathology report findings. Patients grouped according to PSA levels and compared for PCa detection rates, and several parameters. We created 16 prostate biopsy scenarios (S1-S16) and applied these to our database to find out the best biopsy protocol to detect PCa. RESULTS: A total of 336 patients with a mean age of 70.5 (47-91) years were included. Mean PSA level was 190.6 (20-5474) ng/ml. PCa detection rates were 55.3%, 81.0%, and 97.7% in patients with PSA levels 20-49.99, 50-99.99, and ≥100 ng/ml, respectively. PSA level was correlated to clinically more important digital rectal examination findings. We selected 2 cores in S1-S6, 4 cores in S7-S12, and 6 cores in S13-S16. We calculated the sensitivity of each scenario and found that all scenarios in PSA Group 3 had a sensitivity >95%. In Group 2, S8, S10, S13, and S14 and in Group 1, only S14 had sensitivity >95%. CONCLUSIONS: It is not necessary to take 10-12 core biopsy samples in men with PSA levels >20 ng/ml. We recommend taking 2, 4, and 6 samples for patients with PSA levels ≥100 ng/ml, 50-99.99 ng/ml, and 20-49.99 ng/ml, respectively.

The outcomes of Kulkarni's one-stage oral mucosa graft urethroplasty in patients with panurethral stricture: a single centre experience.

PURPOSE: To present the results of our one-stage oral mucosa graft urethroplasty series for panurethral strictures. METHODS: We included the first 35 patients who had one stage oral mucosa graft urethroplasty with one side dissection of the urethra which was described by Kulkarni, between January 2015 and June 2018 and had at least 6 months follow-up. From the first case, all data were recorded prospectively and patient age, etiology of the stricture, comorbidities, previous treatments, postoperative maximal flow rate, pre and post-operative erectile function, perioperative and postoperative complications and quality of life questionnaire for this study. RESULTS: The mean patient age was 58.8 and mean stricture length was 13.6 (10-16) cm. Patients had previously 1-17 procedures. Patients had a mean peak flow rate of 25.4 ml/sec at the first postoperative visit. During the follow-up period, six patients had recurrence and managed with urethral dilation (1), direct vision internal urethrotomy (2), meatoplasty (1) and re-urethroplasty (2). The responses to the questions about satisfaction from the surgery showed that 31 (88.6%) patients were satisfied with the surgery, 33 (94.3%) would prefer this procedure again, if needed, and 31 (88.6%) patients recommended this procedure to others. When patients were grouped according to age, recurrence rate was 35.7% in patients older than 65 years and 4.8% in patients ≤ 65 years old. CONCLUSIONS: Our study showed that Kulkarni's one-stage oral mucosa graft urethroplasty technique has a high success rate. The patient satisfaction is high because of the good functional outcomes and low complication rate.

Can feeling of incomplete bladder emptying reflect significant postvoid residual urine? Is it reliable as a symptom solely?

PURPOSE: The main objective of this study was to reveal the relationship between lower urinary tract symptoms (LUTS) and post-void residual (PVR) urine volume. MATERIALS AND METHODS: Between October 2014 and February 2015, older than 40 years patients were included in this study. Volunteers filled out a questionnaire consisted of demographic characteristics, comorbidities, medications, history of surgery and LUTS. Volunteers were undergone PVR measurement with transabdominal ultrasonography. The relationship between symptoms, demographic characteristics and PVR were analyzed. RESULTS: A total of 939 patients (756 men and 183 women) were enrolled in this study. There was a positive correlation between the sensation of incomplete bladder emptying and PVR volume in all age groups of women (p=0.0001). However such a relationship was found only over the age of 60 in the subgroup analysis of men (p=0.001). PVR volume increased in men by age (0.65 mL per year of age, p=0.011). In men, voiding symptoms and urgency were associated with a high PVR volume. In women, storage and voiding symptoms (except slow stream and terminal dribble) did not correlate with PVR volume. CONCLUSIONS: Our study showed that all men over the age of 60 years and all women with the complaint of feeling of incomplete emptying should undergone PVR measurement. Women with the complaint of poor stream and men mainly with voiding symptoms are other candidates in whom PVR measurement would be considered as an important tool in the clinical management and follow-up.

The renoprotective effects of mannitol and udenafil in renal ischemia-reperfusion injury model.

PURPOSE: The aim of this study was to investigate and compare the effects of udenafil and mannitol in an experimental renal ischemia-reperfusion (I/R) injury model. MATERIALS AND METHODS: A total of 64 female Wister Albino rats were used. Right nephrectomy was performed in all groups. In the control group; I/R injury was not performed. In the I/R group; left renal pedicle was clamped for 45 minutes and then underwent 60 minutes and 24 hours of reperfusion. In the mannitol group; 1 mL 20% mannitol was given intravenously 15 minutes before clamping. In the udenafil group; 10-mg/kg udenafil was given orally 1 hour before clamping. Creatinine (Cr), blood urea nitrogen (BUN), Cr clearance, malondialdehyde, neutrophil gelatinase associated lipocalin (NGAL), histological examination and DNA damage (Comet Assay method) levels were compared in tissue, serum and urine samples. RESULTS: Udenafil had a better protective effect than mannitol according to biochemical parameters (Cr, BUN, Cr clearance, and NGAL levels) and histopathological findings when compared with the I/R group. In the Comet sampling analysis no significant difference was detected. CONCLUSIONS: Udenafil has a better renoprotective effect than mannitol against I/R injury and this effect supports more functional improvements. Further clinical trials are needed to demonstrate those effects and clinical utility of udenafil for that purpose in humans.

Optic-guided vaginal repair of vesicovaginal fistula.

BACKGROUND AND PURPOSE: The transvaginal approach for the repair of vesicovaginal fistula (VVF) can sometimes be challenging, especially in fistulas located near the vaginal cuff. We describe a simple technique for the vaginal repair of VVF with the use of endoscopic optics. PATIENTS AND METHODS: Three women were admitted to our department with urinary incontinence after total hysterectomy. Assessment with a clinical examination, imaging, and cystoscopy confirmed the diagnosis of VVF. All patients were operated on between December 2012 and January 2013. The operations were conducted under spinal anesthesia with the patients in the lithotomy position. Cystoscopy was performed and retrograde pyelography ruled out any ureteral damage or fistula. A 10F to 12F Foley catheter was inserted into the fistula. From this point, the operation proceeded with optic vision, mimicking laparoscopic dissection and suturing techniques using a standard 5 mm, 30-degree optic lens, a surgical monitor, and open surgical instruments. The fistula was circumferentially incised and widely mobilized from the surrounding tissues and closed without tension in two layers. A urethral Foley catheter was inserted and maintained for 14 days. RESULTS: The mean operative time was 70 (range 60-80) minutes. Estimated blood loss was minimal. All patients were discharged at postoperative day 1. No complications were observed. At the postoperative first and third month follow-up visits, all patients were voiding without any urinary leakage or complaints. CONCLUSIONS: The use of optics in the vaginal repair of VVF is a useful technique. Optic guidance facilitates surgical vision, dissection, and hemostasis. It is also excellent for surgeon comfort, ergonomics, and resident training.

Urogenital and Rectal Multisystem Organ Injury After Detonation of an Explosive Substance in the Rectum of a Schizophrenic Man.

Penetrating injuries are caused by the injury of perineal area with gun or stab wounds, which may cause complex injuries or multiple organ injuries. Infections, bleeding, necrotizing fasciitis, ureterocutaneous fistulas, diverticulum, abscesses, narrowing, and incontinence may arise after urethral injuries. Although there are several case reports of urogenital system traumas in the literature, this case reports a schizophrenic patient who had a multisystem genitourinary and rectal trauma after self-detonation of an explosive in the rectum and managed with reconstructive surgery without any postoperative complications. Lower urinary tract anatomy was preserved and full continence was achieved after the surgical procedure.
