OBJECTIVETo compare the incidences of complications associated with 3 different endoscopic procedures, namely transurethral resection of prostate (TURP), bipolar plasmakinetic resection of the prostate (PKRP), and holmium laser enucleation of the prostate (HoLEP) in the treatment of benign prostatic hyperplasia (BPH) and assess the clinical value of the Clavien-Dindo classification system for standardizing the evaluation of the complications.
METHODSBetween January 2010 and December 2013, a total of 625 patients with BPH scheduled for endoscopic surgery underwent TURP (214 cases), PKRP (207 cases), or HoLEP (204 cases). The complications were recorded in each group and analyzed using the Clavien-Dindo classification system.
RESULTSThere was no significant difference in the baseline data among the 3 groups (P>0.05). TURP was associated with a higher total incidence rate of complications than PKRP and HoLEP, and the incidences of electrolyte disturbance, massive intraoperative hemorrhage, urinary irritation symptom, urinary blockage, transurethral resection syndrome (TRUS), and erectile dysfunction (ED) differed significantly among the 3 groups (P<0.05). According to Clavien-Dindo classification, the incidence of grade II complications was significantly higher in TURP group than in PKRP and HoLEP groups (P<0.05), and that of grades III and IV complications was significantly higher in TURP group than in HoLEP group (P<0.05); no significant difference was found in grade I or V complications among the 3 groups (P>0.05).
CONCLUSIONAccording to the results of Clavien-Dindo classification analysis, PKRP and HoLEP are associated with fewer complications with a better safety profile in the treatment of BPH. The current Clavien-Dindo classification system can contribute to standardized evaluation of surgical complications but still needs further modifications for better performance.

Objective:To establish the biology reference interval (RI) of peripheral blood procalcitonin (PCT) for children between 3 days and 6 years old in China.Methods:Totally 3 353 reference individuals with apparent health or no specific diseases were recruited in 18 hospitals throughout the country during October 2020 to May 2021. Reference individuals were divided into four groups: 3-28 days, 29 days - 1 year, 1-3 years and 4-6 years. Vein blood or capillary blood were collected by percutaneous puncture from every reference individual. The PCT level in serum and the capillary whole blood were assayed by Roche Cobas e601 and Norman NRM411-S7 immunoanalyzer. Outliers were deleted and 95th percentiles of every group were provided as RIs. Man-Whitney U test or Kruskal-Wallis test were used performed to assess the difference among different gender, age or method groups. Results:The difference of PCT distribution between male and female is not statistically significant, but the difference between serum and capillary whole blood is statistically significant. The differences between age groups are significant too. For Roche e601, serum PCT RI of 3-28 days group is <0.23 μg/L, 29 days - 6 years are <0.11 μg/L. For NRM411, Serum PCT RI of 3-28 days group is <0.21 μg/L, 29 days - 1 year: <0.09 μg/L, 1 - 6 years: <0.10 μg/L. For whole blood PCT, RI of 3-28 days group is <0.26 μg/L, 29 days - 6 years is <0.15 μg/L.Conclusions:Serum and capillary whole blood PCT have different RIs, however, capillary whole blood PCT testing is valuable in pediatric application. Children in 3-28 days show higher PCT levels than other age group. To establish the RIs and understand the differences among different groups are essential for the interpretation and clinical application of peripheral blood PCT testing results.
