Revolutionizing urology: the advancements and applications of robotic platforms.

Robot-assisted surgery is developing as an acme of minimally invasive surgery, given its utmost dominance over laparoscopic surgery. The objective was to review the status of robotic surgery in urological practice with its advantages and disadvantages in current scenario. We conducted a literature search using MEDLINE and identified 72 articles which were relevant to urology. Single-port and various multiport robotic platforms like Da Vinci, Versius, Hugo RAS, Revo-I, Senhance, Mantra, Avatera, Hinotori, and MicroSurge are described with pros and cons. With a surge in different medical surgical robots purging into the market and a race to become the next standard of care in robotic surgery, it is only a matter of time when robotic surgery becomes financially comparable to laparoscopic surgeries.

Supine versus prone percutaneous nephrolithotomy for renal calculi: Our experience.

Objectives: To compare operative times, safety, and effectiveness of percutaneous nephrolithotomy in the supine versus the prone position. Materials and methods: An observational study of 100 patients was conducted in our institution for 2years from 2018 to 2020 divided into 2 groups: 50 patients underwent modified supine percutaneous nephrolithotomy (PCNL) and 50 patients underwent standard prone PCNL. The inclusion criteria included a renal calculus (calyx or pelvis) of any size for which PCNL was indicated and exclusion criteria were patients having contraindications for PCNL such as bleeding disorders, pregnancy, high risk, and co-morbid conditions. The measured data included operative time, number of punctures, stone-free rate, length of hospital stays, and rate of complications. Results: The 2 groups were comparable in mean age, male to female ratio, calculus size, number of punctures, residual calculi, and postoperative fever and pain. The mean difference of hemoglobin in the supine PCNL group was 0.37 g/dL whereas in the prone PCNL group it was 0.61 g/dL. The p value was significant at 0.043. The mean time to finish from initial postion was 72.24 minutes in supine PCNL and 88.12 minutes in prone PCNL. The p value was significant (p < 0.001). The mean time before puncture was 20.92 minutes in the supine position and 31.84 minutes in the prone position. The p value was significant (p < 0.001). The mean time from puncture to finish was 51.32 minutes in the supine position and 56.28 minutes in the prone position. The p value was significant (p < 0.001). Conclusions: As observed from this study, supine PCNL is associated with a significantly reduced operating time when compared to conventional prone position PCNL procedures. The postoperative complications such as pain and fever were not significantly different. Hence, the supine PCNL is an equally effective modality for treatment of a renal calculus with benefits of simultaneous retrograde access and less operative time compared to the prone PCNL.
