Abstract:
Objective:To investigate the characters and emergency treatment strategy of upper urinary tract stone obstruction complicated with urosepsis.Methods:Clinical data of 28 cases of urosepsis, caused by upper urinary tract stone obstruction and arranged for emergency admission in our hospital during January 2018 to December 2019, were retrospectively analyzed. There were 6 males and 22 females. The median age was 54(32-93)years old. All patients had fever with the temperature ranged from 38.5 to 41.0 ℃. The median course of disease was 3 (ranging 1-14) days. The systolic blood pressure ranged from 76 to 138 mmHg at admission. Hypotension group was defined as the systolic blood pressure<90 mmHg after admission. Normotensive group was defined as the systolic blood pressure≥90 mmHg. There were 12 cases in hypotension group, including 3 males and 9 females. The median age was 57 (ranging 32-93) years old. The stones located at left side in 7 cases and right side in 5 cases. The stones located at the upper ureter in 5 cases, middle ureter in 2 cases, lower ureter in 4 cases and renal calculi in one case. The median length of the stone was 10 (ranging 6-20) mm. Six cases suffered with diabetes mellitus. One case suffered with neuron system disease. 3 cases have history of recent extracorporeal shock wave lithotripsy(ESWL). There were 16 cases in normotensive group, including 3 males and 13 females with the median age of 53 (ranging 33-76) years old. The stones located at left side in 5 cases, right side in 9 cases and bilateral in 2 cases. The stones located at the upper ureter in 10 cases, middle ureter in 4 cases, lower ureter in 2 cases. The length of the stone was 10 (ranging 8-14) mm. There were 3 cases with neurological diseases and 3 cases with recent ESWL history. There was significant difference between hypotension group and normotensive group in ration of diabetes mellitus ( P=0.024). Blood routine examination, C-reactive protein (CRP), procalcitonin(PCT), blood and urine bacterial culture were performed in both groups. The patients were treated with empiric antibiotics after the evaluation based on the sequential organ failure assessment (SOFA). Patients with hypotension were given blood volume expansion, and vasoactive drugs were added when the blood pressure was still low. After the blood pressure was stable, the collection system decompression was performed. The difference of infection indicators and therapeutic methods between the two groups was compared. Results:There was no significant difference in median WBC [16.34 (2.55-41.65) × 10 9/L vs. 13.97(6.23-26.65) × 10 9/L, P=0.577], median CRP [143.0(74.2-200.0) ng/ml vs.110.0 (22.7-200.0) ng/ml, P=0.771] between hypotension group and normotensive group. The difference of PCT [95.5 (26.5-200.0) ng / ml vs. 57.6 (1.0-200.0) ng / ml, P=0.040] and PLT [65.5(14.0-170.0)×10 9/L vs. 73.0(17.0-412.0)×10 9/L, P=0.030] between hypotension group and normotensive group was statistically significant. The median SOFA scores of hypotension group and normotensive group were significantly different [8.5(3.0-13.0) vs. 5.0(2.0-8.0), P=0.001]. Ureteral stent placement was performed in 23 cases, and nephrostomy was performed in 5 cases. There was no significant difference in surgical drainage between the two groups ( P=0.887). Eight patients in hypotension group were admitted to ICU. There was no significant difference in the duration of antibiotic use between hypotension group and normotensive group [8 (3-12) d vs. 5 (3-7) d, P=0.453]. Sepsis was cured in both groups after decompression, fluid resuscitation and antibiotic treatment. Conclusions:In severe cases of upper urinary tract stone obstruction complicated with urogenic sepsis, septic shock may occur. The condition is urgent, severe and dangerous. Patients with hypotension had higher PCT and SOFA scores, and lower PLT. It is very important to carry out the collection system decompression drainage in time, liquid resuscitation, early effective antibiotic use.
