A simple teaching tool for training the pelvic organ prolapse quantification system.

The pelvic organ prolapse quantification (POPQ) system is currently the most common and specific system describing different prolapse stages. Nevertheless, its use is not yet accepted worldwide in routine care. Our aim was to develop a simple teaching tool for the POPQ system capable of simulating different stages of uterovaginal prolapse for use in medical education with hands on training. We constructed a moveable and flexible tool with an inverted Santa Claus' cap, which simulated the vaginal cuff and the tassel at the end representing the cervix. A wooden embroidery frame fixed the cap and served as the hymen, the reference point for all measurements. Inside the cap, we sewed buttons to define the anatomic landmark points Aa and Ap located 3 cm distal from the frame. After explaining the device to the students, we used the three-by-three grid for recording the quantitative description of the pelvic organ support. First, each student had to demonstrate a specific prolapse with his cap device. Then, a prolapse was simulated on the cap, and the student had to take the relevant measurements and record them in the POPQ grid. The main training effect to understand the POPQ system seems to be the possibility for each trainee to simulate a three-dimensional prolapse with this flexible vagina model.

Bleeding complications with the tension-free vaginal tape operation.

OBJECTIVE: This study was undertaken to analyze bleeding problems with tension-free vaginal tape (TVT) operations in a national registry. STUDY DESIGN: We studied patients for whom increased intraoperative bleeding or reoperation for bleeding/hematoma with TVT operation were reported to the registry. RESULTS: Bleeding problems were reported for 151 of 5578 (2.7%) TVT operations. Increased intraoperative bleeding was reported for 106 (1.9%) and reoperation (or conversion) in 45 (0.8%) patients (both in 5 patients). Increased intraoperative bleeding was managed conservatively in 103 patients (95%). Overall, 45 (0.8%) patients required reintervention for bleeding or hematoma. The reinterventions comprised 34 laparotomies, 4 transvaginal evacuations of hematomas, 3 revisions for bleeding from a suprapubic catheter site, and 2 revisions of the vaginal incision (details unclear in 1 patient). Bleeding was considered arterial in 12% (including 1 external iliac artery injury and 1 obturator artery injury) and venous or unknown in 88%. Of reoperated patients, 39% were reoperated within 24 hours, 20% within 2 to 10 days, and 41% within 11 to 56 days after TVT placement. Overall, 19 patients received blood transfusions (range, 1-10 units). There were no deaths from bleeding complications. CONCLUSION: Bleeding complications were reported with less than 3% of 5578 TVT operations. Most cases of increased intraoperative bleeding were managed conservatively; 0.8% of patients required conversion or reoperation.

The urethra during pelvic floor contraction: observations on three-dimensional ultrasound.

OBJECTIVE: To investigate with three-dimensional ultrasound how voluntary pelvic floor contractions influence the morphology of the female urethra's components. METHODS: Twenty female patients with benign gynecologic disorders (mean age: 29 years; range: 19-40) had transrectal sonography using a 7.5-MHz mechanical sector endoprobe with three-dimensional features during both pelvic floor muscle relaxation and pelvic floor muscle contraction. The multiplanar display of the scanned volumes allowed detailed morphologic assessment of the urethra and the measurement of distances and volumes of the urethral components. Statistical end points were maximum sagittal and transverse urethral diameter, maximum sphincter length and thickness, maximum smooth muscle thickness, and the volumes of the sphincter, the smooth muscle, and the entire urethra. RESULTS: All 20 rectal scans were feasible. Two patients had to be excluded from analysis because of poor image quality, leaving 18 patients for evaluation. When compared with pelvic floor relaxation, the following measures were smaller during pelvic floor contraction: sagittal urethral diameter (10.4 versus 11.5 mm; P =.004), transverse urethral diameter (14.1 versus 15.0 mm; P =.009), urethral sphincter thickness (2.4 versus 2.7 mm; P =.012), urethral sphincter volume (0.5 versus 0.6 mL; P =.003), and total urethral volumes (1.4 versus 1.5 mL; P =.007). Sphincter length and smooth muscle thickness, as well as smooth muscle volume, did not change significantly during pelvic floor contraction. CONCLUSION: On three-dimensional ultrasound, the morphologic changes of the female urethra during pelvic floor contraction suggest external compression of the urethra rather than contraction of the sphincter muscle.
