Implementation of a new procedure: laparoscopic versus robotic sacrocolpopexy.

PURPOSE: The purpose of this study was to compare the implementation process and the learning curves of laparoscopic and robotic-assisted laparoscopic sacrocolpopexy (LSC and RSC, respectively) for vaginal apex prolapse. METHODS: A retrospective study of the first 40 LSC and first 40 RSC procedures performed at one medical center. The primary outcomes were intraoperative bleeding, operative time, and hospitalization. Secondary outcomes were surgical complications. The independent t test, paired t test, χ(2) test, Fisher's exact test and Pearson's correlation were used to analyze the data. We assumed that 34 participants were needed in each group to detect a 50 ml or more difference in estimated blood loss between laparoscopic and robotic surgeries, MAIN RESULTS: Age, preoperative pelvic organ prolapse quantification (POPQ) staging, and concomitant medical disorders did not differ significantly by procedure type. For LSC and RSC, the mean estimated intraoperative blood loss was 206 ± 107 and 48 ± 55 ml, P < 0.0001; mean operative times were 176 (110-380 min) and 186 (105-345 min), P = 0.34; and mean length of hospital stay, 3.8 ± 1 and 2.4 ± 1 days, P < 0.0001, respectively. Adverse events were rare, not severe, and did not differ significantly by procedure type. CONCLUSIONS: RSC and LSC are feasible procedures with acceptable complication rates. RSC enables operating more anatomically with less bleeding.

Alterations of heart rate variability in women with overactive bladder syndrome.

INTRODUCTION AND HYPOTHESIS: Our objective was to compare autonomic nervous system function between women with an overactive bladder (OAB) and control participants during regulated bladder filling. METHODS: Twenty-four women, nine with OAB and 15 without (control), were instructed to drink 1.5 l of water at a rate of 250 ml every 5 min during continuous electrocardiogram (ECG) monitoring. Participants were asked to indicate first sensations of filling (FSF), first desire to void (FDV), strong desire to void (SDV), and maximal bladder capacity (MC). ECG signals were used to assess heart rate variability, which were analyzed in time and frequency domains using the fast Fourier transform. The low-frequency (LF)and high-frequency (HF) spectral bands were used to asses sympathetic and parasympathetic pathways, respectively. RESULTS: During the bladder-filling phase, women with OAB had significantly lower LF values (at the MC phase 5.4 ± 1.4 ms(2)/Hz vs. 6.4 ± 0.6 ms(2)/Hz in the control group, p = 0.02). In the control group, LF increased continuously, whereas in the OAB group, LF increased until the sensation of SDV and then abruptly decreased to baseline values. MC was lower in women with OAB (372 ± 153 ml vs. 592 ± 298 ml, p < 0.05, respectively). CONCLUSIONS: Reduced sympathetic tone in women with OAB may explain their attainment of lower volumes of MC and their sensation of urgency. The rapid decrease in sympathetic neural activity that accompanies the sensation of an SDV may be related to the pathophysiology of the urgency symptom in these women.

Is mesh becoming more popular? Dilemmas in urogynecology: a national survey.

The use of vaginal mesh in pelvic organ prolapse (POP) repair surgery has become more common in recent years. The purpose of the current study was to evaluate the common practice of Israeli urogynecologists, and to determine whether surgical practice has changed over the last two years. Methods. In 2009 and again in 2011, a survey was mailed to all urogynecologists affiliated with an academic institute in Israel. The survey consisted of 7 Likert-scale items and 3 open questions; the latter inquired about preferred type of surgery in three clinical scenarios. Results. Of 22 practitioners, 15 responded to the survey. The number of urogynecologists who reported using vaginal mesh for the repair of primary POP increased from 47 to 67% from 2009 to 2011. The number who would not use vaginal mesh in POP repair of elderly patients dropped from 60 to 3%. Finally, for the treatment of a 35-year-old patient with stage III uterine prolapse who desired to preserve fertility, 13% recommended the used vaginal mesh in 2009 compared with 47% in 2011. Conclusion. A survey of practitioners shows that the use of vaginal mesh for the repair of primary and recurrent pelvic organ prolapse has become more common among Israeli urogynecologists.
