Intelligent Pressure‑Control Technology Assists Urology Team in Kidney Stone Removal

A New Therapeutic Option for Kidney Stones

Ureteral stricture, recurrent urinary tract infection after ureteral stent placement, multi‑antibiotic resistance, combined kidney stones and hydronephrosis — these complicated co‑existing conditions signal hidden risks within the urinary system. Recently, the Urology Department team led by Director Ge Jingping at Taikang Xianlin Drum Tower Hospital, Affiliated to Nanjing University Medical School, successfully drained pus and removed stones for a patient with complex urinary tract infection by applying intelligent pressure‑control technology.

Ms. Zhang previously received a ureteral stent for ureteral stricture. After stent implantation, she suffered recurrent urinary tract infections with multidrug‑resistant bacteria, accompanied by hydronephrosis and quail‑egg‑sized kidney stones. After admission and comprehensive evaluation, Director Ge Jingping performed ureteroscopy, which revealed polyp hyperplasia at the ureteropelvic junction. Worse still, pyonephrosis co‑existed with renal calculi inside the renal pelvis.

Under such circumstances, conventional lithotripsy surgery carries risks of infection spread. After thorough assessment and repeated case discussions, Director Ge’s team adopted intelligent pressure‑controlled lithotripsy and stone‑clearing technology. This technique monitors and adjusts renal pelvic pressure in real‑time while simultaneously fragmenting and removing pus and stones intraoperatively. It prevents infection dissemination triggered by uncontrolled intrapelvic pressure in traditional stone‑removal procedures, and spares patients the burden of passing stone fragments spontaneously after surgery. The surgery was completed successfully, and Ms. Zhang was discharged the next day.

Kidney stones remain highly prevalent. Mainstream minimally‑invasive therapies include percutaneous nephrolithotomy and flexible ureteroscopic lithotripsy, yet both have limitations such as uncontrollable intraoperative renal pelvic pressure and limited immediate stone clearance. “Intelligent pressure‑controlled lithotripsy and stone‑clearing technology is suitable for complex infectious stones. Precise pressure control brings a brand‑new treatment alternative for patients,” commented Director Ge Jingping.

Warning: Four Urinary Tract Symptoms That Require Prompt Medical Attention

1. Recurrent urinary tract infections, especially those poorly responsive to antibiotic therapy

2. Lumbago combined with fever, suggestive of renal infection

3. Persistent abnormal urine tests with persistently elevated white blood cell and bacterial counts

4. Kidney stones complicated by hydronephrosis, which easily trigger repeated infections

The urinary tract acts as the body’s vital waste‑drainage system. Seek standardized hospital examinations promptly once any above‑mentioned symptoms occur.
