Non-contrast figured tomography (NCCT) is the imaging methodology of decision while assessing urolithiasis patients. These sweeps are regularly performed preoperatively as it is fundamental to have a CT output to survey stone size and area, and subsequently fittingly plan for the procedure.1 Although this investigation is phenomenal for assessing stone weight, it frequently neglects to describe the renal gathering framework. A comprehension of the gathering framework, including variables, for example, infundibular width, infundibular length, and the points of passage into the distinctive calices from a potential nephrostomy lot or by retrograde ureteroscopy, is significant as this data empowers the specialist to build up the ideal endourological approach. Subsequently, urologists regularly additionally acquire a difference concentrate before percutaneous nephrolithotomy (PCNL) to distinguish the ideal calix of passage. This outcomes in expanded expense and radiation openness. On the other hand, intraoperative retrograde pyelography is performed at the start of a PCNL or ureteroscopic technique, in this manner driving the specialist to devise the careful arrangement at the hour of procedure. No investigations have assessed the utilization of oral hydration and an oral diuretic before NCCT as to planning of the gathering framework.
