Differences in management of pregnant women with obstructing infected ureteral stones: A population‐based analysis. (28th October 2022) - Ha, Albert S.
Abstract : Objectives: Obstructing ureteral stones complicated by urinary tract infection are urologic emergencies that require prompt decompression. We explore the association of pregnancy with rates of and delays in decompression in a cohort of women of reproductive age. Methods: Using the National Inpatient Sample from 2010 to 2015, a cross‐sectional, descriptive analysis of women of reproductive age (15 to 44 years old) diagnosed with obstructing ureteral stones and urinary tract infection was performed and stratified by pregnancy status. Survey‐weighted regression models were used to assess the association of pregnancy on decompression, delays in decompression, and hospital length of stay. Additional exploratory analyses on the association of timing and type of decompression with maternal‐fetal outcomes were performed. Results: A weighted total of 38 783 hospitalizations were identified, with 6.1% of admissions occurring in pregnant women. On multivariable regression, pregnant women with obstructing ureteral stones and urinary tract infection were 38% less likely of undergoing decompression (adjusted OR: 0.62; p < 0.001) compared with nonpregnant women. Among those decompressed, pregnant women had greater odds of delayed decompression (adjusted OR: 2.28; p < 0.001) and longer length of stay (adjusted IRR: 1.11; p = 0.007). Delayed decompression among pregnant women was associated with increased rates of C‐section, early or threatened labor, fetal distress, and umbilical cord complications. Conclusions: Overall, pregnant women had reduced odds of decompression, as well as increased odds of delayed decompression, when compared with nonpregnant women of reproductive age. Delays in decompression among pregnant women were also associated with increased maternal and fetal complications.
