Abstract:
ObjectiveTo explore the advantages and feasibility of visual nephroscope-assisted one-step puncture in the establishment of percutaneous nephrolithotomy （PCNL） channels. MethodsThe clinical data of patients who underwent PCNL in the Affiliated Hospital of Qingdao University from January 2024 to June 2024 were retrospectively analyzed. According to whether the visual nephroscope-assisted one-step puncture was used to establish the percutaneous renal channel， the patients were divided into an observation group （n=32） and a control group （n=50）. The clinical data （such as Guy's stone score of kidney stones， degree of hydronephrosis， number of channels， etc.） and postoperative recovery conditions （such as postoperative complications， degree of hemoglobin decrease， acute kidney injury， etc.） of the two groups were compared. ResultsA total of 51 channels were established in the observation group， and all channels were successfully established. A total of 59 channels were established in the control group， among which 2 cases lost the channel during dilation and were punctured again. There were statistically significant differences between the two groups in age （P=0.049）， number of channels （P=0.034） and size of channels （P<0.001）， while there were no significant differences in other general data. The results of postoperative complications in the observation group and the control group showed that： in the observation group， the incidences of acute kidney injury， systemic inflammatory response syndrome （SIRS）， and pleural effusion were 12.50% （4/32）， 9.38% （3/32）， and 6.25% （2/32） respectively， and the incidences of blood transfusion， embolism， and perirenal hematoma were all 0； in the control group， the incidences of acute kidney injury， SIRS， and pleural effusion were 8.00% （4/50）， 6.00% （3/50）， and 2.00% （1/50） respectively， the incidences of blood transfusion and embolism were 2.00% （1/50 for each）， and the incidence of perirenal hematoma was 4.00% （2/50）. ConclusionVisual nephroscope-assisted one-step puncture may quickly and accurately establish the percutaneous renal channel， which is effective and safe in PCNL.
