Comparison Of The Efficacy Of FURL And SMP In The Treatment Of Renal Calculi With High CT Value ≤2cm In Diameter

Objectives To explore the efficacy and safety of(flexible ureteroscopic lithotripsy,FURL)and(Super-mini Percutaneous Nephrolithotomy,SMP)in the treatment of renal calculi with high CT value less than or equal to 2cm in diameter.Methods Retrospectively analyzed 19,17 and 16 patients with renal stones with diameter less than 2cm and CT value greater than 1200 Hu who underwent percutaneous nephrolithotomy in the Affiliated Hospital of North China University of Science and Technology,Tangshan Workers’ Hospital and Tangshan People’s Hospital from June 2019 to December 2020,respectively,and were defined as the SMP group.Sixty-six patients with renal calculi whose diameter was less than or equal to 2cm and CT value was greater than 1200 HU who were admitted to the Affiliated Hospital of North China University of Science and Technology during the same period and underwent transurethral flexible ureteral lithotripsy were defined as the soft endoscopic group.The general data,operative time(d),postoperative hospitalization time(d),stone clearance rate(%),preoperative and postoperative mean difference in hemoglobin,incidence of pain and fever(%),and hospitalization cost(yuan)of patients in the soft scope group and the SMP group were compared.Results Operation time: The average time in FURL group was(89.45±9.22)min;The SMP group had a mean of(67.83±11.19)min,and the operation time in the soft scope group was longer than that in the SMP group,the differences were statistically significant(P<0.05);Postoperative hospital stay: The average length of hospital stay in the FURL group was(4.42±0.54)d,and the average length of hospital stay in the SMP group was(6.03±0.67)d,respectively(P<0.05).The calculi clearance rate of the FURL group was 89.4%,and that of the SMP group was96.2%.The calculi clearance rate of the FURL group was lower than that of the SMP group,the differences were statistically significant(P<0.05);The mean difference of preoperative and postoperative hemoglobin was(24.41±5.42)g/L in the FURL group and(31.32±5.47)g/L in the SMP group.The comparison of mean difference of preoperative and postoperative hemoglobin between the two groups was not statistically significant(P<0.05);The overall incidence of postoperative pain and fever was 10.6% in the FURL group and 9.6% in the SMP group.The incidence of postoperative pain and fever in the FURL group was higher than that of postoperative complications in SMP,and the results were statistically significant(P<0.05);The average hospitalization cost of the FURL group was(23153.58±2312.61)yuan,and that of the SMP group was(16493.26±1025.54)yuan.The average hospitalization cost of the FURL group was higher than that of the SMP group,and the difference was statistically significant(P<0.05).Conclusions 1 The stone clearance rate of the SMP group was higher than that of the soft lens group;2 The duration of surgery and the overall incidence of postoperative pain and fever in the SMP group were shorter than those in the soft lens group,and the length of hospital stay in the soft lens group was shorter than that in the SMP group;3 There was no statistical difference in blood loss between the soft lens group and the SMP group;4 In terms of hospitalization costs,the SMP group was superior to the soft lens group.Figure0;Table8;Reference 98...
