Clinical efficacy of daily low-dose tadalafil on erectile dysfunction-no sexual life / 中华男科学杂志

<p><b>OBJECTIVE</b>Erectile dysfunction-no sexual life (ED-NS) is defined as the inability to have enough penile erection hardness and duration so as to have enough confidence in attempting sexual intercourse for more than six months. This study was to investigate the effect of daily low-dose tadalafil on ED-NS.</p><p><b>METHODS</b>We treated 35 ED-NS patients aged 17-35 (25.9 +/- 3.9) years with oral tadalafil at 5 mg qd for 3 months and followed them up for another 3 months after drug withdrawal. We obtained the scores of the patients on Self-estimation Index of Erectile Function-No Sexual Life (SIEF-NS) and compared them before and after medication and at 3 months after drug withdrawal.</p><p><b>RESULTS</b>The patients' SIEF-NS scores were 43.2 +/- 7.1 after medication and 42.1 +/- 7.4 at 3 months after drug withdrawal, both significantly higher than 21.2 +/- 5.9 before treatment (P < 0.05), though there was no significant difference between the former two scores (P > 0.05).</p><p><b>CONCLUSION</b>Daily medication of low-dose tadalafil can significantly improve the erectile function of the patients with ED-NS.</p>

Study on multiple aldosterone-producing adenomas / 中华外科杂志

<p><b>OBJECTIVE</b>To investigate the experience on diagnosis and treatment of multiple adrenal aldosterone-producing adenomas (APA).</p><p><b>METHODS</b>Eighteen cases of multiple adrenal APA were analyzed retrospectively, which were admitted from October 1992 to April 2006.</p><p><b>RESULTS</b>Adrenalectomy was performed for 4 cases of unilateral synchronous multiple APA, which were discovered with three adenomas by 3D-CT; bilateral tumor resection was performed for 6 cases of bilateral synchronous multiple APA. There were 8 cases of bilateral metachronous multiple APA, including 2 cases of ipsilateral recurrent adrenal APA after adrenal tumor removal, which underwent tumor resection. Another 6 cases were contralateral APA following adrenalectomy due to adrenal APA, and underwent tumor resection. After operation, the adrenal function seemed to be normal, and no recurrence had been found on follow-up.</p><p><b>CONCLUSIONS</b>Unilateral multiple synchronous APA require adrenalectomy. Tumor resection should be performed for bilateral or asynchronous APA, and it is very important to preserve healthy adrenal tissue as much as possible. 3D-CT has much value on diagnosis of small APA, unilateral multiple synchronous APA and ipsilateral recurrent adrenal APA.</p>

Clinical analysis in diagnosis and treatment of 11 patients with hereditary renal cell carcinoma / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the diagnosis and treatment of hereditary renal cell carcinoma.</p><p><b>METHODS</b>Clinical data of 11 patients with hereditary renal cell carcinoma were analyzed retrospectively. Eight patients were male and 3 were female, age ranged from 32 to 67 (mean: age 48 years). Four cases were bilateral renal cell carcinoma, and 4 were multiple renal cell carcinoma. Two cases were diagnosed as Von Hippel-Lindau syndrome, 6 as familial clear cell renal cell cancer, and 3 as hereditary papillary renal carcinoma.</p><p><b>RESULTS</b>Ten patients performed nephron-sparing surgery and/or radical nephrectomy and 1 had no operation. The patients were followed up from 12 to 114 months. Tumor recurrence was observed in 4 patients, 1 patient died of tumor metastasis, and 2 died of other causes. Four patients survived free of tumor.</p><p><b>CONCLUSIONS</b>Hereditary renal carcinoma appears in the youth, and it is predominantly multiple and bilateral. Nephron-sparing surgery is the standard method of treatment for the patients.</p>

Treatment of glandular cystitis / 中华外科杂志

<p><b>OBJECTIVE</b>To improve the therapeutic results of patients with glandular cystitis.</p><p><b>METHODS</b>One hundred and twenty-seven patients with glandular cystitis were treated according to their different etiological factors. The therapeutic methods included anti-infection, obstruction relief, bladder irrigation, transurethral resection, partial cystectomy, total cystectomy.</p><p><b>RESULTS</b>The patients who were associated stones and foreign bodies (50%) were cured spontaneously with an effective rate of 94%. The effective rate in patients with low urinary tract obstruction was 84%. Patients with simple urinary tract infection (53%) were cured spontaneously after anti-infection therapy. The effective rate, recurrence rate and malignancy rate in patients without associated diseases were 71%, 46% and 21% respectively.</p><p><b>CONCLUSIONS</b>Cystitis glandularis should be treated according to different etiological factors.</p>

Strategy for the diagnosis and treatment of bilateral testicular tumor / 中华泌尿外科杂志

Objective To evaluate the clinical features and the strategy for the diagnosis and treat- ment of bilateral testicular tumor.Methods The clinical data (including the signs and symptoms,imaging studies,tumor markers,treatment modalities and histopatbologic diagnoses) of 10 cases of bilateral testicular tumor from January 1980 to December 2004 were reviewed.Their age ranged from 19 to 58 years(mean,34 years).Of the 10 cases,8 with metachronous and 2 with synchronous testicular tumors were identified.The clinical stages at the primary and secondary tumor diagnosis were:5 cases of stageⅠ,3 of stageⅡ;and 6 cases of stageⅠ,1 of stageⅡ,and 1 of stageⅢ,respectively,in 8 metachronous tumor patients.Two syn- chronous tumor patients were both identified as stageⅠdisease.Histological examination showed the primary tumor (seminoma) in 4 cases and the secondary contralateral tumor (seminoma) in 3.Results Two syn- chronous tumor patients underwent bilateral radical orchiectomy simultaneously,and 8 underwent orchiectomy successively.Retroperitoneal lymph node dissection was performed in 3 cases.Postoperatively,hypogonadism occurred in 10 patients,and 7 of them received androgen replacement therapy.Follow-up ranged from 9 month to 23 years with a mean of 10.5 years.Two patients died of the disease;2 had metastasis (1 of them was alive with metastasis);2 had recurrences and underwent local resection.Conclusions Metachronous bilateral testicular cancers are more common than synchronous bilateral testicular cancers.Seminoma was the most common histopathologic type.Testis-sparing surgery can be performed in selected cases.
