DOUBLE-J URETERIC STENTING IN PREGNANCY
Abstract:
Objective. The objective of the study was to evaluate the internal ureteral drainage with a
double J stent in treating symptomatic obstructive uropathy (lithiasic or physiologic) during pregnancy.
Material and Methods. Between 2011-2017 we retrospective analysed 40 pregnant women who were
admitted with renal colic, flank pain, urinary symptoms and inconstant fever. Renal ultrasound revealed
hydronephrosis with clinical and paraclinical signs of acute pyelonephrytis in 19 (47.5%) patients. The
age of pregnancy was between 20 – 30 weeks. All the cases where monitored by white blood cell count,
serum creatinine levels, urinalysis, and urine culture. All ureteric stents were inserted successfully under
local, spinal or general anesthesia. Antibiotic therapy was associated. Results. A total of 32/40 (80%)
patients had a clinical improvement immediately or soon after intervention. All patients had complete
resolution of the hydronephrosis on follow-up renal ultrasound and regression of hydronephrosis and
urinary symptoms after ureteral stenting. Minor complications were reported as (stent irritation, stent
encrustation, and stent migration). The post-natal evaluation confirmed that 18/40 (57%) patients had
urinary calculus disease 22/40 (55%) patients with physiologic hydronephrosis during pregnancy. All
pregnancies progressed uneventfully and 25/40 (62.5%) women had normal vaginal deliveries. The
ureteric stent was removed 2 weeks after delivery and endoscopic removal of ureteral stone. Follow up
renal ultrasound was normal. Conclusions. Ureteral stenting is a very efficient therapeutic option in
treating pregnant women with renal colic and hydronephrosis. Ureteric double J stenting during
pregnancy can be safe, with good symptom relief and has a low complication rate.
