Evaluation of a tubular mesh and a spiral stent woven from titanium nickel alloy for prostatic obstruction in patients at high risk for surgery. Report of 62 cases.

The use of two urethral stents woven from titanium nickel alloy(TiNi)in the form of a tubular mesh or a spiral stent (both made in China)is described.They were implanted in 62 patients with prostatic ourflow obstruction.All patients were considered contraindicated for surgery.They were divided into a spiral stent group(group 1)treated between March 1992 and May 1993,comprising 35 cases,and a tubular mesh group(group 2)treated between October 1993 and December 1994,comprising 31cases,including four failures in group 1.Thirty-theree out of the 35 patients in group 1were treated successfully.Good results were achieved in eight case(22.8%)and significant improvements occurred in 24(68.5%),giving a total effective rate of 91.3%,with a follow-up of 11to 27 months. Fourteen stents were removed within 6 months after the insertion aned six more were removed within 12 months.The mean effective time of the stent in situ was 10.8 months.All 31 cases in the mesh group were treated successfully.Dramatically goode effects were obtained in 28 cases(over 90%)and distinct improvenents were achived in two, giving a total effective rate of over 96.5%,with a follow-up of 6to 14 months(mean 10.5 months.)Cystoscopy was carried out in 12 patients afer 6 months following the imsertion.The major part of the meshes became covered by urothelium.Compared with the spiral,the mesh makes it possible to insert a prosthesis with a larger diameter and anti-pressure.The spiral,however,can be used as a temporary alternative for the relief of prostatic obstruction.A tubular mesh can work well for the relief of prostatic obstruction and remain in situ without causing major problems for at least 1 year.

直肠肿瘤组织及外周血中前列腺素E_2的含量测定及其临床意义

[目的]观察直肠癌患者肿瘤组织及外周血中前列腺素E2(PGE2)含量变化,并探讨其临床意义.[方法]采用PGE2酶联免疫试剂盒分别测定50例直肠癌患者肿瘤组织、癌旁切缘组织及术前外周血中PGE2含量.[结果]直肠癌组织PGE2含量明显高于癌旁切缘组织,分别为(8.16±2.30),(1.58±0.19)ng/g;低分化直肠癌组织PGE2含量明显高于高中分化癌组织,分别为(8.98±2.24),(5.02±1.65)ng/g;外周血中PGE2含量与直肠癌组织PGE2含量呈正相关(r=0.872);肿瘤直径大于5cm与小于5cm的直肠癌患者外周血中PGE2含量间、低分化与高中分化间差异均有统计学意义.直肠癌组织及外周血中PGE2含量与患者年龄及性别无相关性,与肿瘤部位、浸润深度及临床病理分期亦无相关性.[结论]直肠癌患者肿瘤组织中PGE2含量增高,外周血PGE2含量亦随之增高,外周血PGE2水平与直肠癌组织释放的PGE2含量呈正比;测定外周血中PGE2含量可间接评估直肠癌患者的肿瘤大小与分化程度.
