Ureteroscopic holmium laser lithotripsy for the treatment of renal calyx calculi and its effect on renal pressure

Abstract

Objective To observe the effect of ureteroscopic holmium laser lithotripsy on renal calyx calculi and its effect on renal pelvis pressure. Methods The clinical data of 80 patients with lower renal calyx stones treated in our hospital from August 2016 to August 2017 were retrospectively analyzed and divided into the control group and the observation group, each group with 40 cases. The control group was treated with percutaneous nephrolithotomy, and the observation group was treated with ureteroscopic holmium laser lithotripsy. The perioperative general conditions of the two groups were observed, and the differences of intrapelvic pressure, renal function and complications between the two groups were compared. Results The time of operation and the time of hematuria in the observation group were shorter than the control group, the rate of lithotripsy was higher than that of the control group. There was no difference between the two groups in the intraoperative intraoperative pressure of the renal pelvis; the two groups had no difference in renal function before treatment. After the treatment, the renal function of the two groups had no obvious changes before the treatment. In the 1 month after treatment and 3 months after treatment, the IPSS and QOL were lower than the control group (P<0.05), and the Qmax was higher than that of the control group (P<0.05). There was no significant difference in the incidence of postoperative renal pain, temporary incontinence and urinary tract infection in the two groups (χ2=0.721, P=0.396). Conclusions Ureteroscopic holmium laser litho-tripsy has good therapeutic effect on lower renal calyx stone. It has no adverse effect on renal pelvis pressure and renal function, and can obviously improve the prognosis of the patients. It has good application value.
