Abstract：Objective:To explore the clinical application of blunt dissection through precise puncture of the renal pyramid using contrast-enhanced ultrasound-assisted ultrasound gudiance in nephrostomy for non-hydronephrotic re-nal pelvis.Methods:A retrospective analysis was conducted on 11 patients who underwent ultrasound-guided hydro-nephrostomy in the First Medical Center of the PLA General Hospital from May 2022 to April 2024.Among them,6 patients underwent unilateral pyelostomy and 5 patients underwent bilateral pyelostomy.A total of 16 sides under-went hydronephrocentesis and hydronephrostomy.All 16 sides had no hydronephrosis in the renal pelvis.The success rate of the first puncture,average number of puncture needles,puncture time,total catheterization time,and compli-cations during the puncture process were recorded.Results:All patients were successfully punctured,with a first puncture success rate of 81.25%,an average number of puncture needles of 1.19±0.4,an average puncture time of(122.19±22.55)s,and an average catheterization time of(674.19±46.61)s;All renal pelvis puncture fistulas did not show active bleeding or other serious complications,with two cases having poor drainage and re-adjust the drain-age on the second day after surgery.Conclusion:The ultrasound-guided precise puncture and blunt separation meth-od of the renal cone with the assistance of contrast-enhanced ultrasound has a good application effect in hydronephros-tomy,with high safety and feasibility.It provides a safe and effective treatment method for patients with urinary tract injury who are unsuitable for ureteral stenting,and is worth promoting.
