中文摘要 | 本研究的目的是為了探討腎積水對於用體外震波碎石術來治療近端輸尿管單一顆結石病人癒後之影響。總共 182 位結石大小位於 5 至 20 毫米之間的近端輸尿管單一顆結石的病患在本科接受過體外震波碎石術納入本次的研究。以超音波來定義腎積水的程度。病患人數、結石大小、震波數目及能源也都詳細記錄。在接受過碎石術之後 3 個月來評估治療的癒後。在多變項分析下,只有結石的最大長度 (OR 0.15,95% CI 0.03-0.91,p = 0.04) 及腎積水的程度 (OR 0.40,95% CI 0.16-0.98,p = 0.045) 可當作以體外震波碎石術治療 3 個月之後的結石清除率的預測因子。如果結石的長度小於或等於 10 毫米的輕度腎積水的病患,結石清除率可達到 80%,不過如果腎積水為中度至重度的病患,清除率只能達到 56.4%。如果結石的長度超過 10 毫米的族群中,結石清除率從輕度腎積水的 65.2% 降至中度至重度腎積水的 33.3%。總結來說,在結石長度大於 10 毫米的單一近端輸尿管結石的病患如果同時合併有中度至重度的腎積水,以體外震波碎石術治療似乎癒後並不如預期。因此選擇一些其他的方式如輸尿管鏡取石術或許可以做為這類結石首次或是經過一次體外震波碎石術後仍失敗的病患的治療方式。 |
英文摘要 | The purpose of this study was to investigate the impact of hydronephrosis on the treatment outcome of patients with a solitary proximal ureteral stone after extracorporeal shock wave lithotripsy (ESWL). A total of 182 consecutive patients who underwent ESWL for a solitary proximal ureteral stone of between 5 and 20 mm in size in our institution were included in this study. The degree of hydronephrosis was defined by renal ultrasonography. Patient data, stone size, shock wave numbers and shock wave energy were also recorded. Treatment outcome was evaluated 3 months after the first session of ESWL. In multivariate analysis, only the maximal stone length (odds ratio [OR], 0.15; 95% confidence interval [CI], 0.03-0.91; p = 0.04) and the degree of hydronephrosis (OR, 0.40; 95% CI, 0.16-0.98; p = 0.045) were significant predicting factors for stone-free status 3 months after ESWL. For stones ≤ 10 mm, the stone-free rate decreased from 80% in patients with mild hydronephrosis to 56.4% in those with moderate to severe hydronephrosis. For stones > 10 mm, the stone-free rate decreased further, from 65.2% in patients with mild hydronephrosis to 33.3% in those with moderate to severe hydronephrosis. In summary, patients with a solitary proximal ureteral stone and a stone > 10 mm, the treatment outcome after ESWL was not good if moderate to severe hydronephrosis was noted on ultrasonography. Alternative treatments, such as ureteroscopic lithotripsy, may be appropriate as initial treatment or after failure of one session of ESWL. |
