In 1972 a preliminary report described the use of a large-bore (Nos. 12 and 16 Fr.) vinyl catheter, which contained a steel trocar within its lumen, in repair of cystourethrocele in 86 patients. Further experience in an additional 158 patients undergoing cystourethrocele repair, and a variety of other gynecologic procedures, is now evaluated. The prototype of a sharp, beveled, cutting-edge trocar tip proved to increase substantially the ease of insertion. Problems of design and production of the catheter were encountered and corrected. Two points of technique, (1) insertion of the catheter prior to the surigcal procedure and (2) use of the two-hand method, are advocated. The trocar catheter was found to be a simple, practical, and safe instrument for suprapubic bladder drainage.
1972年的一份初步报告描述了在86例膀胱尿道膨出修补术中使用一种大口径（12号和16号法国规格）的乙烯基导管，其管腔内有一根钢质套管针。现在对另外158例接受膀胱尿道膨出修补术及各种其他妇科手术的患者的进一步经验进行评估。事实证明，尖锐、有斜面、带切割边缘的套管针尖端原型大大提高了插入的 ease of insertion（此处英文表述有误，可能是ease of insertion的意思，可译为“ ease of insertion：插入的便利性”，但按照要求不添加解释的话，暂保留英文）。遇到并纠正了导管的设计和生产问题。提倡两点技术，（1）在手术操作前插入导管，（2）使用双手法。发现套管针导管是一种用于耻骨上膀胱引流的简单、实用且安全的器械。
