Noncystoscopic Removal of Double-J Stent in Women: Feasibility and Safety

Objective

To evaluate the feasibility and safety of a simple noncystoscopic method previously applied in children for removing double-J stents applied in women by comparing the hospitalization time, operation time, costs, complications, and success rate.

Methods

One hundred eighty women who underwent either cystoscopic or noncystoscopic double-J stent removal in a randomized manner. They were randomly assigned 1:1 to groups of cystoscopic double-J stent removal (n = 90) or noncystoscopic double-J stent removal (n = 90). The age ranged from 19 to 72years. After the removal of the double-J stent, the operation time, costs, complications, and success rate were compared between the two groups.

Results

The operation time of the noncystoscopic group was lower than that of the cystoscopic group (6.0(5.0,7.0) minutes vs 2.0(2.0,3.0) minutes, P < .001). The hospitalization costs of the noncystoscopic group were significantly shorter than that of the cystoscopic group (1361.2(1331.4,1379.2) Yuan vs 873.9(868.5,896.1) Yuan, P < .001). There were no complications such as infection and massive bleeding in the two groups during and after the operation. Most noncystoscopic double-J stent removal can succeed in less than three attempts (88/90). All patients in the noncystoscopic group used this technique to remove the double-J stent.

Conclusion

Noncystoscopic removal of double-J stent has the advantages of short operation time and low hospitalization costs. It is a safe and feasible minimally invasive method to replace cystoscopic removal of the double-J stent.
