Gauze is commonly used in surgery. Sometimes strands of gauze are left in situ during surgery. These gauze strands could cause problems later. We report a case of bladder stones secondary to migratory gauze strand postcesarean section. We present a 62-year-old widow who presented with lower urinary tract symptoms of 13-year duration following a cesarean section 15 years before presentation. She had a radiologic diagnosis of multiple bladder stones which on surgical removal, a gauze strand was found to be the nidus for stone formation. A migratory gauze strand from surgery done 15 years before presentation served as a nidus for bladder stone formation in a 62-year-old patient. Surgeons should be careful during pelvic surgeries/procedures not to leave behind foreign bodies like gauze strands that could migrate and cause bladder stones and its attendant sequelae.

| Introduction|| |
Bladder stones account for 5% of all urinary calculi and are rare in women accounting for about 2% of cases.,, When they occur, it is commonly secondary to pelvic infection, previous pelvic surgery including cesarean section, procedures like urethral catheterization and intrauterine contraceptive device (IUCD) insertion, or neurogenic bladder. Therefore, women presenting with a history suggestive of bladder stones should be evaluated for previous pelvic surgery or procedures. Foreign bodies such as IUCD, suture material, or hair have been reported as a nidus for bladder stone formation.
Surgical gauze is commonly used in surgery. Poor surgical techniques by way of the surgeon not removing every foreign body before closing could lead to strands of gauze being left in situ during surgery which could cause problems later as these strands could cause infection or migrate to nearby organs like the bladder where they could serve as a nidus for stone formation. We report a case of multiple bladder stones in a 62-year-old woman with a previous history of a cesarean section where a migratory gauze strand served as a nidus for the stone formation. The case was reported following the Surgical Case Report 2020 guideline.
| Case Report|| |
We present Mrs. OA, a 62-year-old P6+1 (five alive) postmenopausal widow and retired teacher who presented to our general outpatient clinic with recurrent lower abdominal pains, dysuria, and a frequency of 13-year duration. Symptoms were noticed 2 years after her last delivery which was through a cesarean section in a private hospital on account of multiple gestation 15 years before presentation. She then presented to a private hospital where she was diagnosed with bladder stones and placed on liberal fluid intake. Two years later, she noticed she passed some stones while urinating. Symptoms have been recurrent to date when she decided to present to Irrua Specialist Teaching Hospital, a tertiary health facility in Edo State, Nigeria. She was not a known hypertensive or diabetic and had no other significant symptoms of note. She also did not smoke or take alcohol.
On examination, she was afebrile, not pale, anicteric, and not dehydrated. Her pulse rate was 82 bpm and her blood pressure was 110/70 mmHg. Her abdomen was full with a Pfannenstiel scar and suprapubic tenderness. Urinalysis revealed blood ++, urine M/C/S, and serum E/U/Cr were normal. An abdominopelvic scan and abdominal radiograph were done which revealed multiple bladder stones [Figure 1]. A diagnosis of bladder stones was made and open cystolithotomy was done and multiple (6) bladder stones were surgically removed [Figure 2]. Four of the bladder stones were free, whereas the remaining two were attached to the bladder wall by gauze strands. One of the strands is shown in [Figure 2]. The patient had an uneventful recovery with a bladder catheter in situ for 2 weeks. She was discharged 1 week postoperative and had two follow-ups; 2 weeks postoperative when the catheter was removed and 1 month after catheter removal. Both visits were uneventful.
| Discussion|| |
Bladder stones usually occur as a result of obstruction, infection, or foreign bodies. They usually result from migratory kidney stones or urinary stasis in the bladder which could result from bladder outlet obstruction, neurogenic bladder, or foreign body. Bladder stones are rare in women and when present are commonly due to pelvic surgeries where either the bladder was injured or materials used in surgery such as stitches or gauze migrate to cause stones. Our patient was a 62-year-old woman with a previous history of pelvic surgery (cesarean section) where a gauze strand was found intraoperative. The strand is thought to have been from the previous surgery she had.
Our patient presented with lower urinary tract symptoms (dysuria, frequency, and hematuria). This is the common presentation of bladder stones as reported in the literature. These symptoms are also common in patients with urinary tract infection, inflammation, and cancers of the urinary tract like cancer of the bladder. It is important that bladder stones be ruled out in patients with lower urinary tract symptoms through a thorough evaluation including a detailed history and physical examination and appropriate investigations including a cystoscopy where necessary.
Bladder stones could also occur secondary to systemic diseases such as hypertension and diabetes. Wood et al. reported a significant association between systemic diseases such as diabetes and hypertension with the increased risk of urinary stone formation. This is due in part to increased acidity of the urine from elevated uric acid and oxalic acid, leading to the formation of urate and oxalate stones. Our patient was neither hypertensive nor diabetic.
The foreign body in the bladder can act as a nidus for stone formation. There have been reported cases of IUCD; sutures used during pelvic surgeries,, and hair acting as a nidus for stone formation in the bladder. There have been reported cases of IUCDs and abortion sticks migrating from the uterus to the bladder,, and if not detected early could serve as a nidus for stone formation. There is therefore the need for good surgical techniques and adherence to surgical protocols to prevent occurrence. In the case of our patient, the nidus was a strand of gauze which was used during the cesarean section patient had. A similar case of migratory gauze strands following cesarean section was reported in China in a 35-year-old woman. Oduemene and Onuh also reported a case of bladder stones secondary to migratory gauze to the bladder following a hysterectomy. Both patients presented with urinary symptoms and suprapubic pain as noticed in the index patient and were also treated surgically through open cystostomy.
If not promptly diagnosed and treated, bladder stones could lead to recurrent urinary tract infection, cause obstructive uropathy, and could lead to renal disease from ascending infection as a result of urinary stasis.,, There is therefore the need for surgeons to be careful during surgeries, particularly pelvic surgeries not to leave behind any foreign body no matter how small as it could cause problems later as evident in the index patient and others reported in the literature. This can be achieved by adhering to standard surgical protocols during surgeries.
| Conclusion|| |
Bladder calculi occurred secondary to migratory gauze strand from a surgery done 15 years earlier. The gauze strand migrated to the bladder and served as a nidus for bladder stone formation.
Surgeons should be careful during pelvic surgeries/procedures not to leave behind foreign bodies that could migrate and cause bladder stones and its attendant sequelae.
