We reported a case of common channel anomaly complicated with vaginal agenesis and rectal stone, which is a long-term complication of PSARP, a combination of very rare conditions with high morbidity and especially difficult treatment.
A 15-year-old female presented with a chief complaint of cyclic abdominal pain. The patient had no history of menstruation before. Physical examination showed a common channel. The diameter of the common channel was approximately 1 cm and 0.3 cm in length. A sound (±2 mm thickness) was inserted to the small opening between the urethra and anal mucosa with the length of the canal 6 cm. At the end of the opening, a stone-like structure was felt. The management of this case was abdominal hysterectomy with right salpingectomy and stone evacuation.
Cloacal malformation is thought to be associated with vaginal agenesis since both malformations are considered to have a similar pathophysiologic background. Treatment can be performed using posterior sagittal combined with laparotomy approach. After surgery, patients will need a long-term follow-up since the conditions may be associated with many possible urologic and gynecologic comorbidities, including recurrent urinary tract infections, hematosalpinx, and vesicourethral reflux, including stone formation.
Our case was considered one of the most complex common channel anomalies because it was complicated with a rare condition called vaginal agenesis and rectal stone after PSARP. A multidiscipline approach was necessary.
