A new type of operative nephroscope has been developed that possesses the advantages of a fiberoptic scope but with good tactile sensation. The diameter of the scope is 2.3 mm. and its overall length is 770 mm., with a working length of 600 mm. The angle of the visual field is 70 degrees and its depth is 3 to 50 mm. The fiberscope is used in combination with forceps with hollow arms. The instrument is inserted through 1 of the arms of the forceps, while the other arm can be used for irrigation. The fiberscope may be fixed on a stand and, therefore, pyelolithotomy can be done in the conventional manner while the interior of the renal pelvis is observed. The instrument was used for pyelolithotomy in 26 patients with multiple renal stones and to examine the renal pelvis in 16 with drainage by nephrostomy or cutaneous ureterostomy. All stones were removed successfully in all but 1 patient in the former group.
一种新型的手术肾镜已被研制出来，它具有纤维光学镜的优点，但触觉良好。该肾镜直径为2.3毫米，总长770毫米，工作长度为600毫米。视野角度为70度，深度为3至50毫米。纤维镜与带空心臂的钳子配合使用。仪器通过钳子的一个臂插入，另一个臂可用于冲洗。纤维镜可固定在支架上，因此，在观察肾盂内部时，可以按传统方式进行肾盂切开取石术。该仪器用于26例多发性肾结石患者的肾盂切开取石术，以及16例通过肾造瘘术或皮肤输尿管造口术引流的患者的肾盂检查。在前一组中，除1例患者外，所有结石均成功取出。
