Objective To compare clinical outcomes of percutaneous nephrolithotomy (PCNL) in patients who initially presented with and without urosepsis. Methods The study included patients who underwent PCNL for renal and ureter urolithiasis removal from January 2010 to December 2014 in our hospital. A 1∶1 matched-pair analysis was performed to compare outcomes and complications of patients who had obstructive urolithiasis with urosepsis initially (OUU) with patients who had obstructive urolithiasis with no urosepsis initially (NOUU) before PCNL. Results A total of 172 patients were included involving 122 (71%) males and 50 (29%) females with a mean age of 46.2 years (range 32 to 65 years). There were no significant differences between two groups in age, gender, BMI, complications, the size of the stones, stone's number and stone location (P>0.05). OUU groups had the similar stone-free rates (86.0%vs. 84.8%, P=0.829) as the NOUU group. OUU group had higher overall complications rate, longer duration of nephrostomy tube (NT), longer hospital length of stay (LOS), longer courses of postoperative antibiotics and higher grade of antibiotics after PCNL (all P<0.05). Higher fever developed postoperatively (11.6%vs. 3.5%, P=0.043), higher asymptomatic bacteriuria (11.6% vs. 3.5%, P=0.043) and symptomatic urinary tract infections (10.5% vs. 2.3%, P=0.029) were also found in OUU groups. There was no significant difference between two groups in sepsis (2.3% vs. 1.2%, P=0.560). Conclusion PCNL after decompression for urolithiasis-related urosepsis has similar success but higher complication rates than obstructive urolithiasis with no urosepsis initially.
Objective To investigate the diagnosis and treatment strategy of urosepsis caused by ureteral calculi in solitary kidney. Methods The clinical data of patients with urosepsis caused by ureteral calculi in solitary kidney in the Department of Urology of Chengdu 363 Hospital Affiliated to Southwest Medical University from March 2015 to March 2020 were analyzed retrospectively. Results A total of 23 patients were included. One patient received ureteroscopic holmium laser lithotripsy, after which urosepsis and renal function deteriorated, then got better after anti-infection and hemodialysis treatment in intensive care unit; 17 patients received implantation of ureteral stent by cystoscopy, and 5 patients received percutaneous nephrostomy by ultrasound guiding, the 22 patients received ureteroscopic lithotripsy or flexible ureteroscopic lithotripsy electively. One patients had subcapsular renal hematoma postoperatively and worse renal insufficiency, the rest 22 patients had improved renal function. All patients were cured clinically. Conclusions For solitary kidney patients who have urosepsis caused by ureteral calculi, emergency treatment is necessary. The relief of urinary obstruction must be based on effective anti-infection. Choosing cystoscopic ureteral stent implantation or percutaneous nephrostomy depends on patients’ individualization. Ureterscopic lithotripsy simultaneously is not recommended. Ureteral intubation before cystoscopic ureteral stent implantation is important, which can increase the success rate of ureteral stent implantation.
