ABSTRACT

Objective:To discuss the clinical experience and efficacy of minimally invasive anterograde multiple endoscopic treatment of upper urinary tract stones in allograft kidney.Methods:We retrospectively analyzed 14 patients with upper urinary tract stones in allograft kidney admitted to our hospital from June 2018 to August 2020. 8 cases were female and 6 cases were male, with an average age of 47.3±11.1 years. 3 patients had hyperuricemia and four had hypertension and diabetes. The history of renal transplantation was over ten years in 3 cases, three to five years in 4 cases, two years in 3 cases, 1 year in 3 cases, and 4 months in 1 case. 3 patients had a history of RIRS, and the operation was terminated due to severe ureteral tortuosity resulting in failure of sheathing or ureteroscopy. Ureteral stent was performed in 2 cases due to stone obstruction and hydronephrosis. Serum creatinine was normal in 7 patients before operation, and serum creatinine was 91-139μmol/L in 4 patients in the compensatory stage of chronic renal insufficiency. The serum creatinine was 292, 544 and 708μmol/L respectively in 3 patients in the decompensated stage of chronic renal insufficiency or renal failure stage. The preoperative average hemoglobin was 117.5g/L. 3 cases were partial staghorn calculi, 4 cases were single caliceal or renal pelvis calculi, 2 cases were renal pelvis or caliceal calculi with upper ureteral calculi, and 5 cases were renal pelvis or renal caliceal calculi with multiple calculi. Stone size were 1 case of single upper caliceal stone of 0.7cm, 3 cases of lower caliceal stones of 1.5, 1.6 and 2.0cm, 1 case of renal pelvic stone of 1.5cm, 2 cases of middle and upper caliceal stones of 2.8 and 3.1cm, 2 cases of middle and lower caliceal stones of 1.5 and 3.2cm, respectively. 3 cases of middle upper caliceal and renal pelvic stones were 2.2, 2.5 and 2.6cm. 2 cases of renal pelvis with upper ureteral stones were 1.3 and 1.7cm, 0.7 and 0.5cm respectively. Preoperative routine urine examination showed that 9 cases had urinary tract infection, among which 5 cases had positive urine culture. Surgery was performed after therapeutic improvement with sensitive antibiotics. According to the size and distribution of stone, the combination of single access or multi-access PCNL in different diameters was adopted, supplemented by FURS. Surgical methods selection and performance: 2 cases performed in single S-PCNL with stone size were 2.2cm and 2.6cm, 2 cases performed in single M-PCNL with stone size were 1.5cm and 1.5cm, 1 case performed in Needle-perc with stone size was 0.7cm, 2 cases performed in S-PCNL combined M-PCNL with stone size were 2.8cm and 3.1cm, 3 cases performed in S-PCNL combined Needle-perc with stone size were 2.0cm, 2.5cm and 3.2cm, 2 cases performed in M-PCNL combined Needle-perc with stone size were 1.5cm and 1.6cm, 2 cases performed in S-PCNL combined anterograde FURS with stones size were 1.3cm and 1.7cm in allograft kidney and ureter stone were 0.7cm and 0.5cm, a total of 7 kinds of way, and postoperative stone free rate, laboratory indexes (serum creatinine, blood hemoglobin), surgical complications, postoperative hospital stay were analyzed.Results:All 14 patients (mean age was 47.3±11.1 years) were successfully operated. Postoperative examination revealed 1 case had 0.6cm residual stone and it was cleared at the second stage anterograde FURS through the original access. The mean operative time and postoperative hospital stay were 68.2±21.6min and 6.2±1.3 days. Compared with preoperative serum creatinine changes, 2 cases showed slight increase (mean 12.6±0.3μmol/L), 3 cases showed significant decrease (mean 329.6±216.6μmol/L), and the other 9 cases showed no significant change (range<10μmol/L), among which 5 cases showed an increase (mean 5.4±0.7 μmol/L) and 4 cases showed a decrease (mean 3.7±0.4 μmol/L). The mean decrease of hemoglobin was 9.3±4.1g/L. Two patients had fever and their body temperature returned to normal after anti-inflammatory treatment. No blood transfusion, abdominal organ injury or urogenic sepsis occurred.Conclusions:Invasive anterograde multiple endoscopic treatment of upper urinary tract stones in allograft kidney is a single or combined operation using single-channel PCNL, multi-channel PCNL of different sizes and diameters and anterograde FURS according to individual differences, which can effectively reduce renal function injury is safe, efficient and feasible.

ABSTRACT

Objective To investigate the value of heparin-binding protein(HBP) in predicting urosepsis after endoscopic lithotripsy for upper urinary tract stones.Methods From January to November 2018,635 cases of upper urinary tract stones treated by endoscopic lithotripsy in our hospital was analyzed.According to the 2014 edition Chinese Guidelines of the diagnosis and treatment of urosepsis,all patients were divided into two groups,the definite urosepsis group (n =53,8.3%) and the no urosepsis group (n =582,91.7%).The serum of HBP level was detected by fluorescence immunoassay technology.The serum of procalcitonin (PCT) level was detected by cyclic enhanced immunofluorescent assay.C-reactive protein (CRP) level was detected by automatic chemiluminescence immunoassay analyzer.White blood cells (WBC) count was performed by hematology analyzer.Receiver operating characteristic(ROC) curves were constructed by SPSS 22 and MedCale,and areas under curves (AUC) were calculated and compared to illustrate the diagnostic power of HBP,PCT,CRP and WBC.The correlation between HBP and WBC was also significant (r =0.68,P < 0.05).Results The level of HBP,PCT,CRP and WBC were significantly higher in the definite urosepsis group compared to the no urosepsis group.AUC of HBP,PCT,CRP and WBC were 0.930,0.878,0.727 and 0.617.When the cutoff of HBP,PCT,CRP and WBC were set as 51.5 ng/ml,0.41 ng/ml,64.2 mg/L and 11.7 × 109/L,the sensitivities were 89.2%,83.3%,83.5% and 44.7%,and the specificity were 95.9%,75.6%,64.3% and 77.1%,respectively.Conclusions The value of heparin-binding protein was superior to that of PCT,CRP and WBC in predicting urosepsis after endoscopic lithotripsy for upper urinary tract stones.Heparin-binding protein could be acted as a diagnostic marker for urosepsis.

ABSTRACT

4 mm)in the kidney,and were then treated by ESWL combined with oral dissolution agents.The cure rate of this series was 97.7%(86/87).The patients were discharged from the hospital 4 to 16 days(mean,6.3 days)after the treatment.One patient developed massive hemorrhage and was then cured by selective embolization of the small renal vessels.86 patients were followed up for 3 to 18 months(mean,6.3 months),none of them had residual stones during this period.The symptoms of hydronephrosis was improved in all of the cases.Conclusions B-ultrasonography guided MPCNL with holmium:YAG laser is convenient,safe,and effective for upper urinary tract stone.
