Ultrasonography (US) has allowed urologists to safely and constantly survey the kidney and related developments since first involvement in urology in the late 1960s.1 Although giving a careful and noninvasive technique for imaging the kidney, US similarly offers urologists a monetarily insightful intraoperative device fit for recognizing renal perfusion.1–3 Specifically, the introduction of Doppler US modalities has made it possible to accurately distinguish the heading, volume, and speed of renal blood flow. Inferable from their real arrangement, as of now used US tests in urology are limited to surface appraisal of the kidney and its vasculature as they ought to be arranged either on the patient or on the renal capsular surface during a laparoscopic technique. Until this point, an intrarenal US assessment of renal perfusion plans has not been done considering a shortfall of an appropriately assessed Doppler US test. We guess that an examination of this nature would perhaps be of a motivating force for choosing the best site for making an endoscopically guided percutaneous nephrostomy plot. In this assessment, we depict the use of a little novel Doppler transducer that used the working procedure of a versatile ureteroscope.
