Urinary incontinence in a dog with a duplex renal system and extramural ectopic ureter

Presentation, diagnosis, and outcomes of cats undergoing surgical treatment of ectopic ureters

OBJECTIVE

To describe the signalment, treatment, complications, and outcomes of cats treated surgically for ectopic ureters.

STUDY DESIGN

Retrospective, multi-institutional study.

ANIMALS

Twelve client-owned cats.

METHODS

Medical records of cats diagnosed with unilateral or bilateral ectopic ureters were reviewed and analyzed. Data reported included signalment, clinical signs, diagnostics, open celiotomy, or cystoscopic surgical interventions, and outcomes.

RESULTS

Seven of the 12 cats in the study population were female or female spayed and the median age at time of presentation was 4 years, with an interquartile range (IQR) of 6 months-14 years. Presurgical diagnostic imaging diagnosed ectopic ureters by abdominal ultrasound (8/10), contrast enhanced computed tomography (3/3), fluoroscopic urography (3/4), or cystoscopy (6/7). Eight of 12 cats had extramural ectopic ureters and six cats were affected bilaterally. Eight affected cats underwent ureteroneocystostomy, one cat underwent neoureterostomy, two cats underwent cystoscopic laser ablation, and one cat underwent nephroureterostomy. Immediate postoperative complications occurred in three cats; one cat required additional surgical intervention. Short-term complications occurred in three cats, and long-term complications in two cats. All cats that underwent surgical or cystoscopic intervention had improvement of their urinary incontinence scores, with complete resolution in 11 cats.

CONCLUSION

Surgical correction of ectopic ureters in cats is associated with good long-term outcomes. Ectopic ureters in cats are commonly extramural and bilateral. Postoperative outcomes were acceptable and there were few postoperative complications, with varying forms of surgical correction.

CLINICAL SIGNIFICANCE

Ectopic ureters in cats are rare but urinary incontinence can be corrected or improved successfully with surgery.

[Recurrent vaginitis and cystitis due to a vagina and cervix duplex in a bitch - a case report]

Incomplete merging of the Müllerian ducts may result in vaginal septa or even completely separate vaginal canals. It may also cause cervical malformation. In most cases, there are only rudimentary vaginal septations. Only a few reports describing completely separated vaginal canals (vagina duplex) and a cervix duplex in dogs have been published. This article reports the case of a bitch presented with recurrent vaginitis and cystitis. The symptoms always appeared following the dog's heat. The bitch had been pre-treated by a prior veterinarian as well as in a prior clinic. When presented in the clinic, a vaginal septum was suspected based on digital vaginal examination. Ultrasonographic examination and urinalysis allowed for the diagnosis of bacterial cystitis, which was subsequently treated with antibiotics. The bitch was presented again for vaginal endoscopy, transection of the vaginal septum, and ovariohysterectomy. Both vagina duplex and cervix duplex were diagnosed. Due to the extensive dimensions of the findings, the altered tissue was not resected. No more bacteria were detected in a repeated urine analysis. After spaying, the bitch showed no recurrence of symptoms of cystitis or vaginitis.

Laparoscopic treatment of bilateral duplex kidney and ectopic ureter: A case report

BACKGROUND

Duplication of the renal pelvis is a common congenital malformation of the urinary system. About one-third of cases are complete unilateral duplication of the renal pelvis, while bilateral duplication is extremely rare. Herein, we described a single case of bilateral renal duplication with double ureteral orifice ectopic vaginal fistula treated with laparoscopy.

CASE SUMMARY

A 6-year-old girl suffering from long-term vaginal leakage was admitted on June 10, 2018. She was diagnosed with complete duplication of both kidneys and ureters and ectopic opening of both ureters combined with ureterovaginal fistula. The patient received laparoscopic ectopic ureteral bladder replantation and was followed up for 2 years. No renal function damage and vaginal leakage were found.

CONCLUSION

Laparoscopic bladder-ureter reimplantation could effectively determine the location and number of ectopic ureters by imaging and cystoscopy.
