Treatment of urethral strictures using lingual mucosas urethroplasty: experience of 92 cases / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Urethroplasty of complex urethral stricture is a difficult procedure, and there is no widely accepted standard approach described in the published literature. We evaluated the efficacy and safety of urethroplasty using lingual mucosa grafts (LMGs) for the repair of urethral strictures.</p><p><b>METHODS</b>Between August 2006 and April 2009, 92 cases of urethral strictures (length ranging from 2.5 cm to 18 cm, mean 6.5 cm) were treated using LMGs. Of the 92 patients, 38 with long-segment urethral strictures (9 - 18 cm) underwent dual LMG or LMG combined with foreskin flap or buccal mucosal graft urethroplasty.</p><p><b>RESULTS</b>Follow-up was obtained for 3 - 33 months (mean 17.2 months) postoperatively. Complications occurred in 8 patients, including urinary fistulas in 4 patients; recurrent strictures developed in 4 patients at 3 - 4 months post-operatively. The remaining patients voided well postoperatively, with peak flows between 14.3 ml/s and 54.6 ml/s (mean 28.4 ml/s).</p><p><b>CONCLUSIONS</b>The tongue is an excellent source of graft material for the repair of anterior mucosal strictures. Dual LMG substitution urethroplasty can successfully treat longer, more complex urethral strictures.</p>

Adrenal myelolipoma:clinical diagnosis and management of 26 cases / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the diagnosis and management of adrenal myelolipoma.</p><p><b>METHODS</b>The clinical data of 26 cases were analyzed retrospectively and the selected articles were reviewed. There were no specific clinical symptom and endocrine abnormality, except increasing catecholamine in 2 cases. All cases but two were diagnosed by B-model ultrasound scanning (B-US), CT or magnetic resonance imaging (MRI).</p><p><b>RESULTS</b>Twenty-six cases were surgically treated, the diameter of the tumor was 5 - 10 cm, simple tumor resection was performed in 16 cases, and complete adrenal resection was performed in 10 cases. All the operated cases were proved by pathologists. The duration of follow-up was from 6 - 28 months after surgery. No recurrence was observed.</p><p><b>CONCLUSIONS</b>The diagnosis of adrenal myelolipoma could be established based on B-US, CT or MRI. The tumors whose diameter is larger than 5 cm in size should be removed.</p>
