Hydronephrosis, defined as dilation of the renal pelvis and calyces, may occur with scoliosis or after corrective surgery. However, spontaneous resolution of pre-existing hydronephrosis following scoliosis correction has not been previously reported. We present a 12-year-old girl with a mutation, severe thoracolumbar scoliosis (Cobb 103°), and bilateral hydronephrosis. After posterior spinal fusion (T4-L3), hydronephrosis resolved completely. Just as the spinal angle, likely the angle between the renal pelvis and ureter was similarly adjusted, facilitating improved urinary drainage. This rare case highlights a possible dual therapeutic effect of scoliosis correction on spinal alignment and urinary drainage in selected cases.
肾盂积水，定义为肾盂和肾盏扩张，可能与脊柱侧弯或矫正手术后发生。然而，脊柱侧弯矫正后先前存在的肾盂积水自发消退此前尚未见报道。我们报告一名12岁女孩，她存在一种突变、严重胸腰椎脊柱侧弯（Cobb角103°）和双侧肾盂积水。后路脊柱融合术（T4-L3）后，肾盂积水完全消退。正如脊柱角度一样，肾盂和输尿管之间的角度可能也得到了类似调整，从而促进了尿液引流改善。这一罕见病例凸显了脊柱侧弯矫正对特定病例脊柱排列和尿液引流可能具有的双重治疗效果。
