Immediate impact of an intensive one-week laparoscopy training program on laparoscopic skills among postgraduate urologists.

INTRODUCTION: Laparoscopic techniques are difficult to master, especially for surgeons who did not receive such training during residency. To help urologists master challenging laparoscopic skills, a unique 5-day mini-residency (M-R) program was established at the University of California, Irvine. The first 101 participants in this program were evaluated on their laparoscopic skills acquisition at the end of the 5-day experience. METHODS: Two urologists are accepted per week into 1 of 4 training modules: (1) ureteroscopy/percutaneous renal access; (2) laparoscopic ablative renal surgery; (3) laparoscopic reconstructive renal surgery; and (4) robot-assisted prostatectomy. The program consists of didactic lectures, pelvic trainer and virtual reality simulator practice, animal and cadaver laboratory sessions, and observation or participation in human surgeries. Skills testing (ST) simulating open, laparoscopic, and robotic surgery is assessed in all of the M-R participants on training days 1 and 5. Tests include ring transfer, suture threading, cutting, and suturing. Performance is evaluated by an experienced observer using the Objective Structured Assessment of Technical Skill (OSATS) scoring system. Statistical methods used include the paired sample t test and analysis of variance at a confidence level of P

New age teaching: beyond didactics.

Widespread acceptance of laparoscopic urology techniques has posed many challenges to training urology residents and allowing postgraduate urologists to acquire often difficult new surgical skills. Several factors in surgical training programs are limiting the ability to train residents in the operating room, including limited-hours work weeks, increasing demand for operating room productivity, and general public awareness of medical errors. As such, surgical simulation may provide an opportunity to enhance residency experience and training, and optimize post-graduate acquisition of new skills and maintenance of competency. This review article explains and defines the various levels of validity as it pertains to surgical simulators. The most recently and comprehensively validity tested simulators are outlined and summarized. The potential role of surgical simulation in the formative and summative assessment of surgical trainees, as well as, the certification and recertification process of postgraduate surgeons will be delineated. Surgical simulation will be an important adjunct to the traditional methods of surgical skills training and will allow surgeons to maintain their proficiency in the technically challenging aspects of minimally invasive urologic surgery.

Psychosocial impact of renal donation.

PURPOSE: To determine the psychosocial effects of donor nephrectomy on a sample of Canadian donors. MATERIALS AND METHODS: Patients donating one of their kidneys for transplantation at the Toronto Hospital between 1991-1996 were asked to complete a 170-item questionnaire designed to assess their psychosocial well-being and the impact of renal donation on various aspects of their lives. Of the 153 donors contacted, 104 (68.0%) have responded to date. RESULTS: Less than 5% of donors complained of renal donation severely affecting any aspect of their life. Most donors (84%) were able to perform their normal daily activities within 12 weeks of nephrectomy, and 75% had recovered their pre-donation level of work function by this time. Almost one third of donors lost wages because of their donation, and half incurred significant transportation costs. Very few donors (< 10%) complained of other costs. Almost 90% of donors felt that donating a kidney had positively impacted their relationship with the recipient, and donors felt that their relationships with the recipient were significantly more positive at follow-up (p<.003). CONCLUSIONS: Donating a kidney results in a moderate psychosocial impact on the donor and appears to strengthen the bond between donor and recipient. Recovery times to daily activities and work may be longer than anticipated in a large proportion of donors.

Living donor nephrectomy: follow-up renal function, blood pressure, and urine protein excretion.

PURPOSE: To assess the effect of donor nephrectomy on blood pressure, 24-hour urine protein excretion, and renal function. MATERIALS AND METHODS: Of the 198 individuals who donated a kidney between 1991-1996, 101 had their blood pressure, 24-hour urine protein excretion, and serum creatinine concentration levels measured. The mean duration of follow-up was 3.2 +/- 1.6 years (range: 8.5 months to 6.5 years). RESULTS: Serum creatinine concentration was significantly higher (p<.001) at follow-up (107 +/- 20 umol/L) compared to before donation (86 +/- 18 umol/L). When follow-up serum creatinine concentrations were expressed as percentages of their pre-operative values, a gradual decline was observed with time (R= -.380). Diastolic blood pressures (p<.05) and 24-hour urine protein levels (p<.001) were significantly higher at follow-up, however, neither increased with time. The prevalence of hypertension and proteinuria in our donors was no different from that of the general population. CONCLUSIONS: Donor nephrectomy does not impair renal function or result in a progressive rise in blood pressure or urine protein excretion up to 6.5 years after nephrectomy.
