Standardized Duplex Ultrasound-Based Protocol for Early Diagnosis of Transplant Renal Artery Stenosis: Results of a Single-Institution Retrospective Cohort Study.

Transplant renal artery stenosis (TRAS) is the most frequent vascular complication after kidney transplantation (KT) and has been associated with potentially reversible refractory hypertension, graft dysfunction, and reduced patient survival. The aim of the study is to describe the outcomes of a standardized Duplex Ultrasound- (DU-) based screening protocol for early diagnosis of TRAS and for selection of patients potentially requiring endovascular intervention. We retrospectively reviewed our prospectively collected database of KT from January 1998 to select patients diagnosed with TRAS. The follow-up protocol was based on a risk-adapted, dynamic subdivision of eligible KT patients in different risk categories (RC) with different protocol strategies (PS). Of 598 patients included in the study, 52 (9%) patients had hemodynamically significant TRAS and underwent percutaneous angioplasty (PTA) and stent placement. Technical and clinical success rates were 97% and 90%, respectively. 7 cases of restenosis were recorded at follow-up and treated with re-PTA plus stenting. Both DU imaging and clinical parameters improved after stent placement. Prospective high-quality studies are needed to test the efficacy and safety of our protocol in larger series. Accurate trial design and standardized reporting of patient outcomes will be key to address the current clinical needs.

Minimally Invasive Transanal Repair of Rectourethral Fistulas.

BACKGROUND: Rectourethral fistulas (RUFs) represent an uncommon complication of pelvic surgery, especially radical prostatectomy. To date there is no standardised treatment for managing RUFs. This represents a challenge for surgeons, mainly because of the potential recurrence risk. OBJECTIVE: To describe our minimally invasive transanal repair (MITAR) of RUFs and to assess its safety and outcomes. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively evaluated 12 patients who underwent MITAR of RUF at our centre from October 2008 to December 2014. Exclusion criteria were a fistula diameter greater than 1.5cm, sepsis, and/or faecaluria. SURGICAL PROCEDURE: After fistula identification through cystoscopy and 5F-catheter positioning within the fistula, MITAR is performed using laparoscopic instruments introduced through Parks' anal retractor. The fibrotic margins of the fistula are carefully dissected by a lozenge incision of the rectal wall, parallel to the rectal axis. Under the healthy flap of the rectal wall the urothelium is located and the fistulous tract is sutured with interrupted stitches. After a leakage test of the bladder, the rectal wall is sutured with interrupted stitches. Electrocoagulation is never used during this procedure. MEASUREMENTS: Fistula closure, postoperative complications, and recurrence. RESULTS AND LIMITATIONS: Median follow-up was 21 (range, 12-74) mo. Median operative time was 58 (range, 50-70) min. Median hospital stay was 1.5 (range, 1-4) d. Early surgical complications occurred in one patient (8.3%). Recurrence did not occur in any of the cases. Limitations included retrospective analysis, small case load, and lack of experience with radiation-induced fustulas. CONCLUSIONS: MITAR is a safe, effective, and reproducible procedure. Its advantages are low morbidity and quick recovery, and no need for a colostomy. PATIENT SUMMARY: We studied the treatment of rectourethral fistulas. Our technique, transanally performed using laparoscopic instruments, was found to be safe, feasible, and effective, with limited risk of complications.

Pharmacologic treatment in postprostatectomy stress urinary incontinence.

OBJECTIVES: The aim of this study was to assess efficacy and safety of association of duloxetine and rehabilitation compared with rehabilitation alone in men with SUI after radical retropubic prostatectomy (RRP), and to compare continence rate even after planned duloxetine suspension. METHODS: After catheter removal, 112 patients were randomized to receive rehabilitation and duloxetine (group A) or rehabilitation alone (group B), for 16 wk. INCLUSION CRITERIA: postprostatectomy SUI with daily incontinent episodes frequency (IEF) of four or greater. After 16 wk both groups suspended duloxetine/placebo and continued rehabilitation. All patients completed incontinence quality of life (I-QoL) questionnaire and bladder diary. Wilcoxon test was used to analyse changes in IEF and in I-QoL score; Fisher exact test was used to compare continent patients between the groups. RESULTS: Adverse events for duloxetine was 15.2%. 102 men completed the study. There was a significant decrease in pad use in group A. After 16 wk, 39 patients versus 27 were dry (p=0.007). At 20 wk, 4 wk after planned interruption of duloxetine, we observed a U-turn, 23 patients were completely dry in group A versus 38 in group B (p=0.008). Whereas, after 24 wk, 31 in group A versus 41 in group B were dry (p=0.08). The decrease in IEF and improvements in I-QoL scores were significantly greater in group A for the first 16 wk. CONCLUSIONS: The data suggest that combination therapy might provide another treatment option for SUI in men that might increase the percentage of early postsurgery continence.

Uterus-sparing vaginal surgery of genitourinary prolapse employing biocompatible material.

OBJECTIVE: The study presents an original uterus sparing technique for transvaginal repair of total genitourinary prolapse. The technique employs a synthetic mesh of mixed polypropylene and 910 polyglactin fibers. METHODS: The prosthesis creates a support for the cystocele, the cervix and the enterocele. It has four anchoring sites: two at the rear in the sacrospinous ligaments and two at the front in the arcus tendineous of the levator ani muscle. Between February 2001 and December 2004, 24 patients (mean age 66.9 years), presenting symptoms of uterine prolapse, cystocele and enterocele (POP-Q stage III-IV Aa associated to II-III-IV C), were treated with our procedure. Pre- and postoperative parameters were evaluated statistically. RESULTS: No patient had any serious complications. The mean follow-up was 31.1 months (range 6-52). 19 patients (79.1%) have shown excellent results and have been completely cured. In 5 other cases (20.8%), the cystocele was completely cured and there was a significant improvement in the hysterocele and the enterocele. One patient required surgical treatment for postoperative stress incontinence. Statistical analysis of data regarding the pre- and postoperative prolapse stage demonstrated a high degree of objective cure rates (p < 0.0001). CONCLUSIONS: While hysterectomy remains the habitual treatment for severe uterine prolapse, our technique provides a promising alternative solution. It is also significant that there were no complications of erosion or infection associated with the prosthesis.

Effectiveness of early pelvic floor rehabilitation treatment for post-prostatectomy incontinence.

PURPOSE: Urinary incontinence after radical prostatectomy is a significant clinical problem. In this prospective study we investigate the effectiveness of early pelvic floor muscle training (PFMT) on a large population, that had undergone radical retropubic prostatectomy (RRP) at our department. METHODS: 300 consecutive patients who had undergone RRP for clinically confined prostate cancer were randomized in two groups after catheter removal. One group of 150 patients took part in a structured PFMT program. This began before discharge and consisted of Kegel exercises. The remaining 150 patients constituted the control group, they were not formally instructed in PFMT. Incontinence was assessed objectively using the 1 hour and 24 hour pad test, as well as with the ICS-Male questionnaire. All patients who were incontinent after 6 months underwent urodynamic evaluation. RESULTS: In the treated group, 19% (29 patients) achieved continence after 1 month, and 94.6% (146 patients) after 6 months. In the control group 8% (12 patients) achieved continence after 1 month, and 65% (97 patients) after 6 months (p<0.001). Patient age did not correlate with continence in the control group (p>0.05), although a significant correlation was revealed within the treated group (p<0.01). Overall, 93.3% of the total population achieved continence after one year. CONCLUSIONS: After RRP an early supportive rehabilitation program like PFMT significantly reduces continence recovery time.
