Spontaneous right-sided ureterocolic fistula: a rare complication of colonic diverticular disease

Ureterocolic Fistula Involving a Native Kidney and the Sigmoid Colon in a Renal Transplant Recipient

“…Of those cases, none have been documented to involve the native kidney ureter in a renal transplant recipient with hydronephrosis from ligated native ureter post ureteropyelostomy. A UCF is typically detected using urinary symptoms, most often presenting with symptoms including pneumaturia, fecaluria, abdominal pain, and symptoms that mimic a urinary tract infection [ 6 ]. The diagnosis is guided by symptoms and made using retrograde pyelogram, excretory urography which shows contrast material as it enters the bowel, or barium enema which shows contrast media entering the affected ureter [ 2 ].…”

Spontaneous Ureterocolic Fistula between Nonfunctioning Kidney Transplant Ureter and Colon in Setting of Diverticulitis

“…Other notable causes include ureterolithiasis, pyelonephritis, prior surgical intervention, trauma, Crohn's disease, diverticulitis, radiation therapy, and malignancy [5]. Ureterocolic fistula due to diverticulitis is exceedingly rare, with only 11 prior cases reported in the literature to our knowledge [2]. Of those cases, none have taken place in patients with nonfunctioning kidney transplant ureters.…”

“…Diagnosis of ureterocolic fistula is dependent on the functional status of the affected urinary system. Importantly, most ureterocolic fistulas will present with both urinary symptoms such as urinary tract infection, pneumaturia, and fecaluria, and abdominal pain [2,6]; however, in the setting of a nonfunctional transplant ureter and kidney, urinary symptoms are less likely. Thus, awareness of this complication in absence of characteristic symptoms is key when considering the differential for abdominal pain in this population.…”

“…The formation of fistulas in the setting of a diverticular disease is relatively rare, occurring in only 1% of cases [1]. Fistula formation with the ureter is particularly rare, with only 11 previous cases reported in the literature [2]. Ureterocolic fistulas most commonly affect the left ureter given its proximity to the sigmoid colon.…”

Ureterocolic Fistula Secondary to Diverticulitis of the Sigmoid Colon after Laparoscopic Salpingo-Oophorectomy: A Case Report and Literature Review

“…A ureteric calculus complicated by obstruction and pyelonephritis is the most common cause. An extensive literature search utilizing PubMed and Ovid databases from 1960 through 2019 revealed that there have been only twelve other published cases of spontaneous ureterocolic fistula secondary to diverticulitis [10–21]. Table 1 summarizes the features of all the twelve cases.…”
