ARTICLE HIGHLIGHTS
Research background
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.
Research motivation
When surgery is necessary, the relationship between timing of the operation and the outcome of the mother and child are not known.
Research objectives
To investigate the association between time to ureteral stent placement and clinical outcomes of patients with renal colic during pregnancy.
Research methods
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.
Research results
PANP was closely related to hospitalization costs, re-admission to hospital due to urinary tract infection after surgery and premature delivery. Multivariate analysis showed that stone location and time from pain to admission were related to PANP.
Research conclusions
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.
Research perspectives
Delayed surgery does not affect clinical outcomes, but leads to longer hospital stay. Time from pain to hospitalization and location of the stones are risk factors for preoperative acute pyelonephritis. Our research will have important significance in the clinic.
