Prospective Randomised Study

Purpose: To evaluate the feasibility, safety and efficacy of one-shot dilation (OSD) in percutaneous nephrolithotomy (PCNL). Materials and Methods: In a prospective randomised study including 62 patients divided into two groups, the first had RD before PCNL using the standard metallic telescopic dilators (Alken), and the second had RD using the 30-F Amplatz dilator over the central Alken dilator. The operative duration, with X-ray exposure, was calculated. The procedure outcome in terms of complications, stone-free rates and hospital stay was evaluated statistically. Results : The tract was dilated correctly in all cases. The operative duration and X-ray exposure was shorter in patients undergoing single-step RD (P < 0.05). There were perioperative complications, according to the Clavien grading system, in 15 (25%) patients but there was no statistically significant difference between the groups. The stone-free rates were comparable in both groups. Conclusion : A single-step RD during PCNL is feasible, with a shorter operative duration and X-ray exposure. The outcomes were comparable with those of a standard metallic telescopic RD Bangladesh Journal of Urology, Vol. 20, No. 2, July 2017 p.70-73

Objective: We aimed to investigate the prevalence of utilization of different endourological instruments and disposables among Egyptian urologists and to see how availability could affect the deviation from the universal standards that might result in reduced patient safety. Patients and method: We surveyed members of the Egyptian Urological Association by a questionnaire evaluating the importance of different instruments and disposables used during ureteroscopy and percutaneous nephrolithotomy. All responses were collected by a commercially available Internet-based survey host ( www.surveymonkey.com ) over 8 weeks. Results: One hundred and fifty-two responses were received. For ureteroscopy, the most mandatory instruments and disposables included the C-arm device (83%), Dormia basket (61%), ureteral stone forceps (58%), pneumatic lithotripter (50%), and regular PTFE guide wire (49%). The instruments and disposables described as optional included 4.5 Fr ureteroscope (74%), flexible ureteroscope (70%), and hydrophilic guidewire (67%). For percutaneous nephrolithotomy, the most mandatory instruments and disposables were pneumatic lithotripter (78%), Alken metal dilator (75%), fascial dilator (45%), and regular PTFE guidewire (42%); while instruments and disposables described as optional included flexible cystoscope (70%), hydrophilic guidewire (67%), balloon dilator (57%), and laser machine (52%). Conclusion: The prevalence of the utilization of newly introduced instruments and disposables is low among Egyptian urologists.
