Role of transurethral resection of the prostate simulators for training in transurethral surgery.

PURPOSE OF REVIEW: Transurethral surgery is an art unique to urologists; mastering the craft is essential for day-to-day practice. Medical treatment along with minimally invasive treatments have significantly reduced the number of transurethral resection of prostates. Decrease in resident's training hours, expanding subspecialties and the emergence of newer technologies have burdened the trainees who are trying to digest the ever-expanding medical literature. Moreover, expectations from patients and insurance companies with a stress on cutting costs and raising litigations have brought changes in apprentice-based to simulator-based training. We studied the role of transurethral resection of prostate simulators in training of transurethral surgery. RECENT FINDINGS: TURP simulators from bench to virtual reality computer models are available. Most of them have undergone face, content and construct validity. Nontechnical skills training is also important hence simulation to simulator training. Simulation programmes incorporating communication, team building, minimizing errors caused by distraction and managing complex situations can turn a novice into an expert with adequate practice in a stress-free environment. Work is also done to define learning curve, and factors affecting the path to reach the desired goal. Concepts are emerging to integrate simulators and simulation into the existing training programmes. SUMMARY: TURP simulators are essential for training in transurethral surgery. Low or high-fidelity simulators do not matter, but having a well structured simulation programme, under the scrutiny of a dedicated trained faculty, will address most of the issues related to training in transurethral surgery, an art essential for urologists irrespective of the subspecialty one pursues in the future.

Comparative study of graft nephrectomy in pre-cyclosporine and cyclosporine era.

OBJECTIVE: To assess the incidence and identify the indications for graft nephrectomy (GN) in the cyclosporine (CSA) era as compared to GN in the pre-CSA era. MATERIALS AND METHODS: This is a retrospective study of 1,866 renal transplants done from 1971 to 1999. 675 were transplanted in the pre-CSA era (group 1) and 1,191 in the CSA era (group 2). The published series on experience with GN in the pre-CSA era was compared with that in the CSA era. GN done within 6 months of transplant was defined as early GN and those done after 6 months were included under late GN. The incidence, indication and the implications of GN were studied and compared with our experience in the pre-CSA era. Results were analyzed using the chi(2) test. RESULTS: Of the 675 transplants in group 1, thirty-one had GN compared to 15 of 1,191 in group 2. There was a significant decrease in GN in the CSA era. Of the 31 in group 1, thirty had early GN as compared to 6 of 15 in group 2 (p = 0.003). On the contrary, late GN was significantly higher in group 2 (9/15) as compared to group 1 (1/31). Acute rejections and graft infections were the predominant causes of graft loss in group 1, while late graft loss due to symptomatic chronic rejection was the commonest cause in group 2. Morbidity was equal in both groups while mortality was significantly higher in group 1. CONCLUSION: CSA has significantly reduced the need for GN. By reducing hyper, acute, and irreversible acute rejection, the need for early GN has also been reduced significantly. Though there is an increased incidence of chronic allograft nephropathy, late GN is indicated only when there is refractory hematuria, intractable proteinuria and graft sepsis. With better immunosuppression, graft loss secondary to infection has decreased and mortality due to GN has been minimized.
