Objective
To investigate the usage of intelligently pressure-controlled flexible ureteroscopy
(URS) in managing upper urinary tract calculi in patients with a solitary kidney.
Methods
Forty patients with a solitary kidney and upper urinary tract calculus were included
in this study. All the patients underwent suctioning URS with intelligent control
of renal pelvic pressure by connecting pressure-measuring suctioning ureteral access
sheath to an irrigation and suctioning platform. Treatment outcome and perioperative
data were collected.
Results
The mean operative time was 25.2 ± 14.5 minutes. The mean hospital stay was 4.7 ± 1.4
days. The stone-free rate at 4 weeks after surgery was 87.5%, and it was 92.5% at
12 weeks after surgery. Two patients (5%) experienced complications of fever postoperatively.
There were no complications of elevated serum creatinine, severe bleeding, sepsis,
stone street, ureteral mucosa stripping, and ureteral stenosis.
Conclusion
It is safe and efficient to use the intelligently pressure-controlled flexible URS
in treating upper urinary tract calculi for patients with a solitary kidney with advantages
of high lithotripsy efficacy and low complication rate.

- PreviewWe have read the article published by Huang et al1 with enormous interest, in which they introduce a novel technique treating upper urinary tract calculi for patients with a solitary kidney. As is known, maintaining a stable intrarenal pressure (IRP) is crucial to a safe operation as increased IRP is closely associated with various complications.2,3 This new technique intelligently ensures a steady IRP through a special ureteral access sheath (UAS), thus improving lithotripsy efficacy and reducing complication.

- PreviewI read the article by Huang et al1 with great interest, in which they suggested to use a novel intelligent pressure-controlled flexible ureterorenoscope (fURS) for stone treatment in solitary kidneys. Being novel equipment, it might open new horizons in renal stone management. As is known, stone volume, stone location, and increased intrarenal pressure during operation are some of the most important factors that reduce fURS success and effectiveness. Increased intrarenal pressure is also associated with various complications such as septic complications and hemorrhage.
