Objectives: Urinary incontinence is one of the major drawbacks of radical retropubic prostatectomy (RRP). One of the possible reasons for this urinary incontinence is a postoperative deficiency of the rhabdosphincter (RS). It has been recently demonstrated that reconstruction of the posterior aspects of the RS allows a rapid recovery of continence after RRP. This study evaluated the application of this technique in videolaparoscopic radical prostatectomy (VLRP), assessing the percentage of continent patients at 3, 30, and 90 d after catheter removal., Methods: A two-arm prospective comparative trial was carried out with 31 patients recruited for each arm. Group A underwent standard VLRP and group B underwent VLRP with RS reconstruction (VLRP-R). Continence was defined as no pads or one diaper/24h and was assessed 3, 30, and 90 d after the procedure., Results: At catheter removal, 74.2% versus 25% (p=0.0004) of patients were continent with the VLRP-R technique versus VLRP, respectively. A statistically significant difference was present at 30 d (83.8% vs. 32.3%; p=0.0001) At 90 d the difference, although still present, was not statistically significant (92.3% vs. 76.9%; p=0.25)., Conclusions: In this preliminary report, the posterior reconstruction of the RS appears to be an easy and feasible technique even in a laparoscopic setting. Time to continence recovery was significantly shortened.

Study Design: Prospective study., Objectives: To evaluate the feasibility of color ultrasound imaging of the urethra in association with UPP to diagnose intrinsic sphincter deficiency (ISD)., Setting: Italy., Methods: We studied a group of 13 normal female volunteers (mean age 29 years) during the estrogenic phase and a group of 15 patients (mean age 63.9 years) with ISD. All patients and normal volunteers underwent color ultrasound imaging using a 4-7 MHz convex broad band transducer. Translabial sagittal scans of the urethra were obtained. The color ultrasound parameters were optimized for detection of parenchymal slow flows. A subjective score of the degree of vascularization along the entire urethra was established as follows: (a) minimal or absent (1), (b) poor (2), (c) moderate (3), (d) good (4). Statistical analysis, using the non-parametric Mann-Whitney rank sum test, was carried out to determine differences of ultrasound scores between volunteers and patients., Results: The statistical evaluation showed that the differences between the ultrasound scores in the two groups was statistically significant (P<0.001)., Conclusion: We affirm that color ultrasound imaging of the urethra seems to be feasible and useful in association with UPP in the diagnosis of ISD even if this echographic investigation needs further observations.

Objective: To assess urethral vascularization in healthy young women, using colour Doppler ultrasonography., Subjects and Methods: Eleven healthy young women volunteers (mean age 33.6 years, range 24-46) with no pelvic floor disorders and no history of incontinence were assessed. The subjects underwent colour Doppler ultrasonography using a 4-7 MHz convex broadband transducer. Translabial sagittal scans of the urethra were taken when the subjects had a full bladder, both during the oestrogenic and progestogenic phases. The colour Doppler ultrasonography parameters were optimized to detect slow flows in the anterior and posterior distal, middle and proximal urethra. A rank-sum nonparametric test was used to assess differences between the resistive indices., Results: The statistical evaluation showed a significant difference in the resistive index only in the anterior urethra, between the distal and middle plus proximal urethra, in both the progestogenic (P = 0.002) and oestrogenic (P = 0.0127) phases., Conclusions: This study confirmed that the vascularization of the urethra plays an important role in the 'seal' effect, which is considered one of the most important factors in urethral closure. There was a significantly greater resistive index in the anterior proximal urethra than in the middle and distal urethra. These findings suggest that the seal effect is related to the existence of a rich venous urethral vascularization, involved in the mechanism of urethral closure. Colour Doppler ultrasonography of the urethra seems to be feasible and useful for understanding the mechanism of the vascular component in female continence.
