RESUMEN
Objective To compare the effectiveness of ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy in treatment of bladder calculi. Methods Clinical data of 76 cases of bladder calculi patients were collected from January 2013 to December 2015. All the patients were randomly divided into two groups: Group A was performed by ureteroscopic lithotripsy via urethral Peel-away sheath (n = 45). Group B was transurethral ureteroscopic lithotripsy (n = 31). Results 76 cases of bladder calculi were successfully treated by one-time lithotripsy. Lithotripsy time: group A was (17.8 ± 5.9) min, group B was (22.7 ± 8.3) min (t = 2.96, P = 0.004); stone clearance time: group A (12.6 ± 4.9) min, group B (24.5 ± 5.3) min (t = 9.90, P = 0.000);Intraoperative urethral mucosa injury : group A (1.0 ± 0.5), group B (2.1 ± 0.4) (t = 9.47, P = 0.000); VAS score:group A (1.9 ± 0.6), group B (2.6 ± 0.6) points (t = 4.72, P = 0.000); indwelling catheter time: group A (1.0 ± 0.2) d, B group (1.4 ± 0.9) d (t = 2.59, P = 0.012); There was no significant difference in hospitalization expense, group A was (7437.4 ± 356.7), group B was (7296.8 ± 333.8) (t = -1.73, P = 0.087). There were no complications such as hemorrhage, perforation and rupture of the 2 groups, without convertion to open surgery either. After the treatment of oral antibiotic, 1 case of postoperative urinary tract infection was cured in group B. In our study, case of postoperative urinary retention was 1 in group A, versus 5 in group B, with statistical difference (χ2 = 6.43, P = 0.011). Follow up: 13 patients were lost to follow-up, the other patients were followed up for 6 ~ 12 months. There was 1 case of elderly male patient with urinary retention due to BPH in each of the 2 groups, the other patients had no recurrence of calculus. By analyzing the statistical results, it was found that the experimental group had obvious advantages over the control group in the lithotripsy time, stone clearance time, urethral mucosa injury, postoperative pain and postoperative indwelling catheter time. Conclusion There is no significant difference in efficacy of the treatment of bladder calculi between ureteroscopic via urethral Peel-away sheath and transurethral ureteroscopy. However, our study shows the Peel-away ureteroscopy has the advantages of shorter lithotripsy time, shorter time of stone clearance and less injury of urethra mucosa menbrane, there was no significant difference in operation cost between two groups. Therefore, Ureteroscopic via urethral Peel-away sheath is an effective method for endoscopic bladder lithotripsy.
RESUMEN
Objective To explore the clinical significance of Nano-Carbon particles and 3D laparoscopy in central compartment lymph node dissection and parathyroid glands protection in treatment of cN0 thyroid cancer. Methods We conduct a retrospective analysis of sixty-five patients with cN0 thyroid cancer who were received 3D laparoscopic thyroidectomy in the last 3 years. All patients were received total resection of thyroid plus the affected side and (or) contralateral side central compartment lymph node dissection. All patients were allocated to control group (n = 32) and carbon nano-particles trace group (tracer group, n = 33). The lymph node-related indexes (including number of dissected lymph node at Ⅵ area, number of Metastatic lymph node and Frozen lymph node-positive rate at Ⅵ area), serum calcium (24 h after surgery) and PTH (48 h after surgery) were collected and compared between the 2 groups. Results Number of dissected lymph node at Ⅵ area, positive rates of intraoperative frozen-section examination of parathyroid glands and PTH (48 h after surgery) were found statistical higher in nanoparticles group than control (P < 0.05). No statistical difference were found in Number of Metastatic lymph node and serum calcium (24 h after surgery) (P < 0.05). Conclusion The clinical significance of carbon nanoparticles and 3D laparoscopy is effective and feasible for central compartment lymph node dissection and parathyroid glands protection in treatment of cN0 thyroid cancer.
