RESUMO
Percutaneous nephrolithotripsy is the first line treatment for complete staghorn calculi, but there are risks such as renal function damage, bleeding, and infection. A case of complete staghorn calculi 8.3 cm×4.5 cm and mean CT value of 1 321 HU was reported. Urine culture suggested proteus mirabilis infection. The patient was given sensitive antibiotics for 3 days, and was treated with one session of natural orifice transluminal endoscopic lithotripsy with intelligent control of renal pelvic pressure. KUB on the first postoperative day showed residual stones of 1.0 cm×0.5 cm. There were no complications.
RESUMO
Objective To compare the safety and efficacy of oblique supine position and lithotomy position in suctioning flexible ureteroscopic lithotripsy. Methods 82 patients with upper urinary calculi were divided into two groups. Group 1 included 47 patients who were treated by suctioning flexible ureteroscopy in oblique supine position. Group 2 included 35 patients who were treated in lithotomy position. There was no significant statistical difference in age, gender and complications between the two groups before surgery (P > 0.05). The operative time, stone-free rates at postoperative 30 d, renal pelvic pressure (RPP), postoperative complications (graded by the Clavien system) and length of stay were compared. Results Retrograde Intrarenal Surgery (RIRS) was successful in 73 cases, and 9 cases of patients were done successfully after indwelling DJ tube 2 weeks. Compared with lithotomy position, a significantly greater stone-free rate of 30 d, shorter operative time (P 0.05). Conclusions Suctioning flexible ureteroscopic lithotripsy in the oblique supine position is safe, and more effective than supine lithotomy position.
