The diagnosis 30 years later
The 61-year-old Quechua woman complained of lower abdominal pain and frequent urination. Due to the chronic complaints, urologist Dr. Benjamin Zeier performed a cystoscopy. He discovered a stone and succeeded in removing the corpus delicti by crumbling it.
A close examination of the bladder wall revealed the remains of a knot of sutures that had stimulated stone formation. In her medical history, the patient stated that she had undergone a caesarean section in 1995. The MRI further clarified the situation. A surgical knot (in this case suture material that does not dissolve) had drilled through the bladder wall from the outer wall of the uterus over the years.
The two red arrows indicate the location in question. Below the bladder with fluid (white color). Above, the uterine wall (black color). The connection (thread) is whitish due to the accompanying edema in the tissue.
