Short-term "double natural orifice catheterization": Nonoperative management of hydrocolpos in persistent cloaca patients - case series.

PURPOSE: Management of hydrocolpos in cloaca patients is of clinical importance. We report a nonoperative method for the management of hydrocolpos in the form of initial catheter decompression, followed by an endoscopy with catheters placement into both the bladder and vagina, and leaving these catheters for 9 and 14days respectively.

METHODS

The medical records of six cloaca patients with hydrocolpos in the last 12years were reviewed. The outcomes measured were the renal function, bladder emptying, the presence/resolution of hydronephrosis, and the recurrence of hydrocolpos.

RESULTS

Complete drainage of hydrocolpos was achieved in four out of six cases and partial drainage in two. On common channel endoscopy, in four patients the structures were identified and balloon catheters inserted. After catheter removal, the vagina and urinary tract remained adequately drained through the natural cloacal opening with no post-micturition residual urine, resolution of hydroneprosis within 60days, preserved renal function, and no hydrocolpos reaccumulation.

CONCLUSION

Initial decompression and short time catheterization can be the definite solution for some cloaca patients with hydrocolpos. Our case-series showed a success rate in two-thirds of patients by achieving the three main goals; permanent hydrocolpos derivation, undisturbed voiding, and preservation of renal function.

LEVEL OF EVIDENCE: Study can be classified as a Treatment Study, LEVEL IV Case series with no comparison group.
