A pyelotomy is a surgical procedure that involves making an incision into the renal pelvis, which is the central cavity of the kidney responsible for collecting urine from the calyces. This procedure is typically performed to explore the renal pelvis for any signs of disease or injury. The renal pelvis serves as a conduit for urine, allowing it to drain into the ureter, which then transports urine to the bladder. During a pyelotomy, a skin incision is made over the kidney, followed by the incision of Gerota's fascia, which is the connective tissue surrounding the kidney. The perirenal fat is then carefully dissected to expose the kidney and ureter. Surgeons identify and control blood vessels by placing loops around them to prevent excessive bleeding during the procedure. The ureter is traced upward to the ureteropelvic junction (UPJ) to locate the renal pelvis. Once located, the posterior aspect of the renal pelvis is incised, allowing for direct exploration of the area. This procedure is crucial for diagnosing conditions affecting the renal pelvis and can lead to further interventions if necessary.
