“…Researchers have reported that staghorn stones usually cause upper urinary tract obstruction and UTI [ 34 , 35 ]. When the urinary tract is obstructed, the various strains of bacteria on the surface of the stones are colonized and grow in large numbers in the renal pelvis [ 36 ]. Our findings are consistent with the idea that when stones are crushed, a substantial release of UTI-causing bacteria and their toxins occurs.…”

“…[ 25 ] When the urinary tract is obstructed, the bacteria on the surface of the stones are difficult to excrete outside the body and grow in large numbers in the renal pelvis. [ 26 ] When the stones are crushed, the urinary tract infection-causing bacteria and toxins contained in the stone will be released in large quantities, and enter the blood circulation through the damaged renal pelvic mucosa, causing infection and fever.

Percutaneous nephrolithotomy (PCNL) is commonly used for the treatment of upper urinary calculi in clinical setting, and fever is a common complication after PCNL. It is necessary to evaluate the risk factors of fever in patients undergoing PCNL, to provide insights into the management of PCNL. Patients who underwent PCNL in our hospital from January 2018 to August 2020 were included. The clinical data of postoperative fever and no fever patients were collected and assessed. Logistic regression analyses were conducted to analyze the risk factors for fever in patients undergoing PCNL. A total of 276 patients undergoing PCNL were included, the incidence of postoperative fever for patients undergoing PCNL was 19.39%. No significant differences in the gender, body mass index, alcohol drinking, smoking, hypertension, hyperlipidemia, intraoperative blood infusion, length of hospital stay between fever patients, and no fever patients were found (all P > .05). There were significant differences in the age, diabetes, size of stones, duration of surgery between fever patients, and no fever patients (all P < .05). Age ≥60 years (odds ratio [OR] 2.143, 95% confidence interval [CI] 1.101∼3.264), diabetes (OR 2.218, 95% CI 1.176∼4.642), size of stone ≥2 cm (OR 1.428, 95%CI 1.104∼2.055), duration of surgery ≥100 minutes (OR 1.334, 95% CI 1.015∼1.923) were the risk factors for fever in patients with PCNL (all P < .05). Escherichia coli (48.44%), Staphylococcus aureus (18.75%), and Candida albicans (10.93%) were the top 3 pathogenic bacteria of urine culture. Fever is one of the common complications after PCNL. Patients with high-risk factors should be given full attentions and take corresponding preventive measures targeted on risks.

“…Micro-Percutaneous Nephrolithotomy refers to PCNL under needle-like visualised nephroscopy, which is a new method of minimally invasive treatment for lower calyceal stones. 3 However, a single application of Micro-Percutaneous Nephrolithotomy to treat lower calyceal stones leads to the risk of high intrapelvic pressure due to the lack of sheath and washing fluid drainage. Meanwhile, when applying transurethral FURL alone to treat 1-2 cm lower calyceal stones, in the case of a limited infundibulopelvic angle (IPA), the ureteroscope may not reach the lower calyx, resulting in intraoperative difficulty with lithotripsy.…”

Objective: To investigate the safety and efficacy of Micro-Percutaneous Nephrolithotomy(Micro-PCNL) combined with flexible ureteroscopic lithotomy(FURL) in the treatment of 1-2 cm symptomatic, refractory lower calyceal stones. Methods: A retrospective analysis was performed concerning the clinical data of 28 patients with 1-2 cm symptomatic, refractory lower calyceal stones. When there was a difficulty in performing FURL in Affiliated Hospital of Hebei University from January 2019 to February 2022, ultrasound-guided F4.8 visual puncture was performed on the lower calyceal stone,with a holmium laser was then used to treat the remaining stones, followed by drainage using a flexible ureteroscopic sheath and postoperative indwelling of the ureteral stent without a nephrostomy tube. The surgery time, intraoperative bleeding and stone-free rate(SFR) were recorded, and the VAS score was used to evaluate the patients’ pain status. Results: The surgery was completed successfully in an average of 43.46 ± 10.04 minutes, and the puncture time was 3.46 ± 0.69 minutes. The SFR was 85.71%(24/28) and 92.86%(26/28) at one day and 30 days after surgery, respectively. Two patients with residual stones greater than 0.6 cm in size underwent extracorporeal shock wave lithotripsy four weeks after surgery. Patients were followed up for three months after surgery, and the SFR was revised to 96.43%(27/28). In addition, the VAS scores of all patients decreased significantly from before to after surgery, and the difference was statistically significant(p< 0.05). Conclusion: Micro-Percutaneous Nephrolithotomy (Micro-PCNL) combined with FURL is safe and effective in the treatment of 1-2 cm symptomatic, refractory lower calyceal stones. doi: https://doi.org/10.12669/pjms.39.6.6782 How to cite this: Shi XQ,Ma T,Wang W, Cui Z, Li X, Gao Y.
