Pregnancy with renal colic may cause pyelonephritis, decreased renal function, systemic infection and even shock in pregnant women, and cause premature birth and other adverse pregnancy outcomes. When surgery is necessary, the relationship between timing of the operation and the outcome of the mother and child are not known.
To investigate the association between time to ureteral stent placement and clinical outcomes of patients with renal colic during pregnancy.
In this retrospective study, pregnant women with renal colic who underwent surgery were studied. Maternal preoperative acute pyelonephritis (PANP), pregnancy outcome, and length of hospital stay (LOS) were compared between the two groups.
100 patients were included in the analysis, median age was 30 years. Median time to ureteral stent placement was 48 h (interquartile range, 25-96 h), and 32 patients (32%) were diagnosed with PANP. PANP was closely related to hospitalization costs, re-admission to the hospital due to urinary tract infection after surgery and premature delivery. Multivariate analysis found that stone location and time from pain to admission were related to PANP.
Both early and delayed surgery are safe and effective for the treatment of renal colic during pregnancy. Early surgery may be superior to a delayed procedure due to shorter LOS. For pregnant patients with renal colic, delayed surgery within 48 h is not related to the clinical outcome of the mother and child. However, the time from pain to hospital admission was related to PANP.
Core Tip: Acute renal colic is one of the most common reasons for pregnant women to be hospitalized for non-obstetric reasons. Renal colic in most patients is resolved after conservative treatment. However, when conservative treatment fails, active surgical treatment is necessary, thus the choice of the timing of the operation is very important. In this study, we examined the relationship between the timing of the operation and the outcome of the mother and child.
