ABSTRACT
Objective To evaluate the effect of one step flexible ureteroscopic lithotripsy for incarcerated upper ureteral calculi.Methods The clinical data of 80 cases of incarcerated upper ureteral calculi were retrospectively analyzed between August 2015 and September 2016.Theone step flexible ureteroscopic lithotripsy was used in 40 cases (one step group),including 22 male cases and 18 female cases.The average age was (40.0 ± 9.5) years.The maximal stone diameter was (i.8 ± 0.5) cm.The widest width of the ureter above the stone was (2.5 ± 1.1) cm.The CT value of stone was (1 089.0 ± 111.3) HU.Two step method was used in 40 cases (two step group),including 21 male cases and 19 female cases.The average age was (41.0 ± 10.7).The maximal stone diameter was (1.7 ± 0.6)cm.The widest width of the ureter above the stone was (2.3 ± 0.9) cm.The CT value of stone was (1 002.0 ± 97.2) HU.During the one step flexible ureteroscopic lithotripsy,only flexible ureteroscope was used to crush the stone,no matter whether the stone located in the ureter or return to the renal pelvis.During two stepmethod,the rigid ureteroscopy was firstly used for crushing the stone in the ureter.When the stone return to the renal pelvis,the rigid ureteroscopy was change into flexible ureteroscope for continuous crushing the stone.Compared two groups' operating time,2 weeks stone clearance rate and the cases of fever after operation.Results The mean operative time in the one step group was (37.45 ± 11.34) min.The mean operative time in the two step group was (55.07 ± 13.57) min.The difference was statistically significant (P ＜ 0.05).The number of infection 2 cases in one step group and 9 cases in two step group.The difference was statistically significant (P ＜ 0.05).2 weeks stone clearance rate was 87.5％ (35/40) in one step group and 82.5％ (33/40)in two step group.There was no significant difference between two groups.Conclusions Flexible ureteroscope one step method is a safe and effective alternation for incarcerated upper ureteral calculi.
ABSTRACT
Objective To investigate the safety and efficacy of percutaneous nephrolithotomy ( PCNL ) combined with ureteroscopy in supine anterolateral lithotomy position for the management of complicated upper ureteric calculi . Methods From January 2009 to October 2012, 67 patients underwent PCNL combined with ureteroscopy in supine position under general anesthesia . Renal calculi was treated with PCNL , and then ureteroscopy was used to break and wash out the residual calculi . Results All the 67 surgeries were completed successfully .Operation time was 46 -106 min ( average, 76 min); stone clearance rate was 92.5%(62/67);residual stone was found in 5 cases and were completely removed two weeks after ESWL .No massive hemorrhage , ureteral avulsion, pleura, abdominal organ injury or other complications occurred . Conclusions PCNL combined with ureteroscopy in supine anterolateral lithotomy position for the treatment of complicated upper ureteric calculi is safe and effective .It has shorter operative time and is convenient for the patients .
ABSTRACT
To compare the efficacy and morbidity of laparoscopic ureterolithotomy and open ureterolithotomy via the posterior lumbar approach. Meterials and Methods: A retrospective study was performed by reviewing patient records. Ten patients in the laparoscopic ureterolithotomy group were compared with 15 patients in the open ureterolithotomy via lumbotomy incision group. Twelve patients who had flank ureterolithotomy comprised a control group. Details of age, sex, size and site of the stone, haematocrit, blood urea nitrogen, serum creatinine, degree of hydronephrosis of the affected kidney, contralateral renal function, operative time, operative complication, the amount of postoperative analgesics and length of hospital stay were all compared. Statistical analysis was carried out by the Chi- square test, Anova and LSD multiple comparisons. Results: The preoperative status of the three groups were similar. When the ureterolithotomy via lumbotomy group was compared with the control group (flank ureterolithotomy) the results were similar except that ureterolithotomy via lumbotomy required less analgesics postoperatively (mean 50 mg vs 104, p < 0.001). Ureterolithotomy via lumbotomy patients required the same analgesics as laparoscopic ureterolithotomy. However, laparoscopic ureterolithotomy had a longer operating time (mean 181.5 min vs 88, p < 0.001) and longer period of urine leak postoperatively (mean 6.6 days vs 2.4, p < 0.003) when compared with ureterolithotomy via lumbotomy. Conclusion: Ureterolithotomy via lumbotomy offers similar low discomfort postoperatively compared with laparoscopic ureterolithotomy but had a shorter operating time and less complications.
