Methods: In August 2010 and April 2012, the LESS nephrolithotomy technique was applied to treat two patients with a renal calculus. One patient had a calculus measuring 5 × 3 cm, and the second patient's measured 3 × 3 cm. Both patients underwent general anesthesia. The operations were performed through a retroperitoneal approach with a single-port instrument inserted through the retroperitoneal incision. The standard laparoscopic retroperitoneal technique was performed, and the calculi were removed by incising the area of the thin renal cortex and the renal pelvis, respectively. The operating time, estimated blood loss, intraoperative complications, other complications, drainage time, and post-operative hospital stay were recorded. Results: Both procedures were completed successfully. No additional trocars were added. No conversion to standard laparoscopic or open surgery was needed. The operating times were 130 min and 120 min, and the estimated blood losses were 40 mL and 30 mL. There were no intraoperative complications. The wound drainage times were 3 d and 2 d, respectively and the post-operative hospital stays were 8 d and 7 d, respectively. There was no secondary bleeding or wound infection. Follow-up times were 2 years and 3 months, respectively. No incidence of hydronephrosis was recorded. Conclusions: LESS nephrolithotomy is safe and feasible for treating kidney calculi. It can be applied in patients with large renal calculi and regionally thin renal parenchyma.展开更多

Positron emission tomography/CT (PET/CT) examination showed multiple lesions in the seminal Vesicles, parapharyngeal space, mediastinum and spermatic cord. The result of transrectal ultrasound (TRUS)-guided biopsy indicated a diffuse, large, B-cell lymphoma of the seminal vesicles. PET-CT and TRUS guided biopsy were very helpful to make the correct diagnosis of this unique case.展开更多
