    ABSTRACT: To evaluate the feasibility of a novel transvesical port (TVEP) for natural orifice translumenal endoscopic surgery (NOTES) in the porcine model. The TVEP consisted of an internal guide core and external sheath design using computer-aided design software. Transvesical peritoneoscopy, renal biopsy, as well as combined transvesical/transgastric nephrectomy were performed through the TVEP in a porcine model. Operative parameters and port performance were measured. Twelve procedures were successfully performed by four surgeons. No complications occurred with introduction of the TVEP. The mean time for placement was 5.6 minutes. Steady pressure controlled CO(2) pneumoperitoneum up to 15 mm Hg with a flow of 2‚ÄČL/min was achievable. The average scoring by physician of the TVEP was 4.75 for ease of placement, 5 for ability to maintain pneumoperitoneum, 4.25 for convenience of inserting instruments, and 4.5 for overall satisfaction. The average score regarding instruments exchangeability, however, was relatively low: 3.25. Real surgery using a novel TVEP is feasible in performing transvesical NOTES.

    ABSTRACT: It is difficult to withdraw an encrusted urinary catheter, especially when it is impacted in the prostatic urethra. This article reports our experience with removing an encrusted urethral catheter using holmium laser through the suprapubic cystostomy tract.

    ABSTRACT: Adrenal ganglioneuroma (GN) is extremely rare. The present study is to describe the largest series of this adrenal tumor treated in a single medical center to our knowledge. Clinical details, radiologic, laboratory, and pathologic findings as well as follow-up data were analyzed retrospectively in 17 patients with incidentally discovered adrenal GN who received operative resection at a tertiary referral hospital in eastern China between June 1999 and June 2009. The mean age of the 17 GN patients was 39.2 years (range, 7-72; male:female ratio, 1:2.4), of whom 13 patients had unilateral GN on the right side, and the remaining 4 on the left side. None of the 17 tumors was hormonally active. Only 6 of the 17 GN cases were diagnosed as benign nerve cell tumors by computed tomography or magnetic resonance imaging before operation. Treatment consisted of open unilateral adrenalectomy in 9 patients and laparoscopy in 8 patients. The mean pathologic size of the adrenal GNs was 6.3 +/- 3.1 cm (range, 1.0-13.0). Ultrastructural examination provided additional support for confirming the diagnosis. Although there have been some clues for radiologic diagnosis of adrenal GN, pre-operative mis- and maldiagnosis are not infrequent. We recommend that complete operative resection should be considered once malignancy cannot be excluded by pre-operative evaluation. Laparoscopic adrenalectomy is a reasonable option at least for tumors < or =7 cm.
