Flushing back stones of the lumbar or iliac ureter towards the renal cavities by means of a catheter is now part of everyday practice. The ureteric flush-back technique is often easily performed when the appropriate equipment is used wisely. We used a 23 Ch cystoscope with a 5 degrees lens to work in the axis of the ureter and a 7 Ch catheter with a single orifice is advanced as far as the stone. In 30% of cases, the stone immediately ascends as far as the renal cavities due to ureteric distension. In the case of failure, rapid injections of physiological saline with a syringe are successful in 40% of cases. In 10% of cases, success depends on progressive hydraulic distension of the ureter above the stone following injection of physiological saline.
通过导管将腰段或髂段输尿管结石向肾腔回冲如今已成为日常操作的一部分。若能明智地使用合适设备，输尿管回冲技术通常易于实施。我们使用带有5度镜片的23F膀胱镜沿输尿管轴线操作，并将单孔的7F导管推进至结石处。在30%的病例中，由于输尿管扩张，结石会立即升入肾腔。若失败，用注射器快速注射生理盐水在40%的病例中取得成功。在10%的病例中，成功取决于在注射生理盐水后对结石上方输尿管进行渐进性水囊扩张。
