Validity of a sponge trainer as a simple training model for percutaneous renal access.

OBJECTIVE: To evaluate the efficacy of our simply designed trainer for junior urologists to acquire the initial skills for percutaneous renal access (PRA). SUBJECTS AND METHODS: Three sponge sheets (60 × 50 × 10 cm) were arranged horizontally over each other. A rectangular groove was made in the middle sheet to accommodate an inflated balloon of a Foley catheter, radio-opaque metal balls, metal rings, or a plastic tube that were sequentially placed for the four training tasks. In each session, 18 trainees were asked to pass a fluoroscopically guided puncture needle from a surface point to the placed object in middle sheet. Clinical impact of training was evaluated by an experience survey on a 5-piont Likert scale (for model usefulness, tactile and fluoroscopic-guidance feedback) and success rate in further mentored practice. RESULTS: There was a gradual increase in tasks' and sessions' scores over the training sessions. According to the experience survey after first clinical practice, the mean (SD) score for overall model usefulness by trainees was 3.8 (0.9) with high fluoroscopic guidance reality [3.6 (1.1)] but poor tactile realism [2.3 (0.9)]. On mentored PRA, the success rate for trainees was 78.3%. CONCLUSION: Our early evaluation showed our novel, cost-effective and reproducible sponge trainer could be an effective training model for PRA with a beneficial impact on subsequent clinical practice.

Immediate and late management of iatrogenic ureteric injuries: 28 years of experience.

OBJECTIVE: To evaluate the long-term results after managing intraoperative and late-diagnosed cases of iatrogenic ureteric injury (IUI), treated endoscopically or by open surgery. PATIENTS AND METHODS: Patients immediately diagnosed with IUI were managed under the same anaesthetic, while those referred late had a radiological assessment of the site of injury, and endoscopic management. Open surgical procedures were used only for the failed cases with previous diversion. RESULTS: In all, 98 patients who were followed had IUI after gynaecological, abdominopelvic and ureteroscopic procedures in 60.2%, 14.3% and 25.5%, respectively. The 27 patients diagnosed during surgery were managed immediately, while in the late-referred 71 patients ureteroscopic ureteric realignment with stenting was successful in 26 (36.6%). Complex open reconstruction with re-implantation or ureteric substitution, using bladder-tube or intestinal-loop procedures, was used in 27 (60%), 16 (35.5%) and two (4.5%) patients of the late group, respectively. A long-term radiological follow-up with a mean (range) of 46.6 (24.5-144) months showed recurrent obstruction in 16 (16.3%) patients managed endoscopically and reflux in six (8.3%) patients. Three renal units only (3%) were lost in the late-presenting patients. CONCLUSION: Patients managed immediately had better long-term results. More than a third of the late-diagnosed patients were successfully managed endoscopically with minimal morbidity. Open reconstruction by an experienced urologist who can perform a complex substitutional procedure was mandatory to preserve renal units in the long-term.

A progressive extended protocol for the basic laparoscopic training using the pelvitrainer.

UNLABELLED: Abstract Purpose: We describe an extended training program using the pelvitrainer to improve the basic laparoscopic skills of the junior urologists. MATERIALS AND METHODS: Ten junior residents were involved in our program that consisted of an hour of training every other day; every 3 hours represented one training session. This curriculum started with 4 inanimate tasks that included peg transfer, disc cutout, extracorporeal, and intracorporeal knot tying. Each task was practiced for one training session with an objective evaluation at the initial attempt and at the end of its session. Thereafter, the participants began to perform an anastomosis using a latex glove model of the laparoscopic urethrovesical anastmosis (L-UVA) (5 experiments). This was followed by 10 experiments of the sheep intestine model of the L-UVA. The performance in these models was evaluated by both the amount of leakage of the injected saline and the time required for completing it. Lastly, another sheep intestine model was performed 3 weeks after the end of the training program. RESULTS: The continuous evaluation of these trainees showed that there was a significant decrease in the time required to perform each of the first 4 tasks at the end of their corresponding sessions compared to the base line values (p=0.000). We also detected a significant decrease in the time and the amount of leakage in sheep intestine models in the 10th attempt compared to the first one (p=0.000). However, there was no significant difference between the results at the 10th model and those of the 3 weeks retest regarding both the time (p=0.198) and the amount of leakage (p=0.076). CONCLUSIONS: The use of the two described models of the L-UVA after the inanimate tasks in the pelvitrainer distributed course of training could help in the improvement and in the retention of the basic laparoscopic skills of the junior urologists.

Sexual function among women with stress incontinence after using transobturator vaginal tape, and its correlation with patient's expectations.

OBJECTIVE: To evaluate changes in female sexual function after a transobturator vaginal tape (TOT) procedure for treating genuine stress urinary incontinence (SUI), and its correlation with patient's expectation. PATIENTS AND METHODS: The study included women treated with a suburethral TOT for genuine SUI, neurologically intact, heterosexual and married, aged >18 years, with no previous history of malignancy, pelvic radiotherapy and no other associated surgical or psychological diseases. Patients were interviewed before surgery and with the aid of a questionnaire including female sexual function, the Beck depression indices and their expectation of sexual function after surgery. RESULTS: Sixty-two premenopausal sexually active women were included (mean age 40.5 years). The cure rate from SUI was 92%, 89%, 87% and 84% at 6, 12, 18 and 24 months, respectively. All patients attended the visit before and the first visit after surgery, while 71%, 42% and 24% were assessed at the 12-, 18 and 24-month visits, respectively. The mean follow-up was 12 months. Fifty-two women resumed their sexual activity early within the 8 weeks after surgery and the frequency of coitus in more than two-thirds of patients was at least once per month. The number of women who expected either looseness or tightness of the vagina was more than that estimated from patient perceptions. There was a difference between the patient's sensation of vaginal length abnormalities during coitus (two women) and patient expectation (18 women). CONCLUSION: Although the TOT is effective for treating SUI, counselling the patient and her partner is important in correcting false ideas and expectations about future sexual activity. Indeed, sexual dysfunction is reported after vaginal surgery, with a physiological and psychological background. Further assessment should be used to characterize sexual dysfunction after vaginal surgery for SUI to find new solutions.
