“…[20] RIRS is associated with a small but significant risk of injury to the delicate pediatric ureters. [21] In a series of 170 children undergoing flexible ureteroscopy, 57% required passive dilatation of the ureter for 1-2 weeks before ureteroscope could be inserted into the ureter.…”

Current role of microperc in the management of small renal calculi

et al. 2013

‘Microperc’ is a recently described technique in which percutaneous renal access and lithotripsy are performed in a single step using a 16 G micropuncture needle. ‘Mini-microperc’ is a further technical modification in which an 8 Fr sheath is used to allow insertion of ultrasonic or pneumatic lithoclast probe with suction. The available evidence indicates that microperc is safe and efficient in the management of small renal calculi in adult and pediatric population. It can also be used for renal calculi in ectopic kidneys and bladder calculi. The high stone clearance rate and lower complication rate associated with microperc make it a viable alternative to retrograde intrarenal surgery.

“…The microperc procedure, which is performed through a smaller tract, has led to lesser parenchymal and vascular damage within narrow infundibula, and calyces resistant to dilatation [3,4]. Kaynar et al [8] shared the results of the microperc procedure they performed for the treatment of a 2-year-old infant with a renal stone. The authors reported that the microperc technique was a safe and efficient procedure.…”

During infancy, the renal parenchyma and pelvicalyceal system are relatively fragile. Therefore, percutaneous nephrolithotomy for the management of renal stones in this age group is a challenging procedure for urologists. Herein, we present the uneventful management of bilateral renal stones using micropercutaneous nephrolithotomy (microperc) administered to a 7-month-old infant with recurrent urinary tract infections. In this paper, the advantages and disadvantages of the microperc procedure are discussed. As far as we know, our patient is the youngest case in whom the microperc procedure has been performed.

Micropercutaneous nephrolithotomy is a safe and efficient technique for appropriate sized stones. It is performed through a 4.85 Fr all-seeing needle and stones are fragmented into dust, without the need for tract dilatation, unlike other percutaneous nephrolithotomy types. Even though micropercutaneous nephrolithotomy has many advantages, increase in intrapelvic pressure during surgery may cause rare but serious complications. Herein we report a case of micropercutaneous nephrolithotomy in a 20-year-old woman with a 20 mm right renal pelvis stone and present an undesired outcome of this complication, upper calyceal perforation. Right lower calyceal access was performed with 4.85 Fr all-seeing needle and 2 cm renal pelvis stone was fragmented by 272 μm Holmium-Yag laser system. Upper calyceal perforation and infrahepatic accumulation of stone fragments were detected by fluoroscopy during the surgery. Postoperative imagings revealed perirenal urinoma, perirenal and infrahepatic stone fragments, and lower calyceal stone fragments inside the system. On second postoperative day, minipercutaneous nephrolithotomy and double J catheter insertion procedures were applied for effective drainage and stone clearance. Risk of calyceal perforation and urinoma formation, due to increased intrapelvic pressure during micropercutaneous nephrolithotomy, should be kept in mind.
