1/14. Cutaneous nephrocolonic fistula as a consequence of a kidney stone.We report an unusual case of cutaneous nephrocolonic fistula caused by a renal calculus with perirenal infection. The diagnosis was made by fistulography and computed tomography, after which nephrectomy and resection of the descending colon were successful. We also review the literature on cutaneous nephrocolonic fistulas.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
2/14. Acute acalculous cholecystitis associated with cholecystoduodenal fistula and duodenal bleeding. A case report.Although acute acalculous cholecystitis (AAC) accounts for less than 10% of acute cholecystitis in the adult population, gangrene and perforation are much more frequent compared to the usual cases of acute cholecystitis (calculus cholecystitis). However, spontaneous biliary-enteric fistula is well recognized in AAC, 90% of which are cholecystoduodenal fistula (CDF) though it is an uncommon disorder. The majority of the CDF are caused by cholelithiasis. As patients are usually associated with complicated clinical illness, the diagnosis is often difficult to make and required surgery is often delayed. We have studied a rare complication of acute acalculous cholecystitis which was presented as intermittent upper gastrointestinal bleeding. Ulceration of the superficial branch of the cystic artery has been observed due to acalculous cholecystitis associated with a cholecystoduodenal fistula. We have performed a transfixing ligation of the bleeding vessel, cholecystectomy and simple closure of the CDF. We have finally made a diagnosis of early gallbladder cancer through a frozen section. There was no serious complication after the operation and the patient has achieved an uneventful recovery.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |

Nephrocolic fistula in association with a staghorn calculus discovered intraoperatively.A rare case of spontaneous nephrocolic fistula discovered intraoperatively in a patient with a staghorn calculus is presented with a review of the literature.- - - - - - - - - - ranking = 5keywords = calculus (Clic here for more details about this article) |
4/14. Spontaneous pyelo-jejunal fistula.This case report describes a patient with a spontaneous jejunal fistula. This is a rare type of nephro-intestinal fistula with only two previously recorded similar cases. Our patient presented with such a fistula diagnosed by antegrade pyelography, associated with a staghorn calculus and proven at surgery. The value of antegrade pyelography is discussed along with the treatment options and the outcome to be expected in such patients.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
5/14. Migration of a ureteric calculus to the bladder via a ureterocolic and a vesicocolic fistula.Following a difficult nephrectomy for pyonephrosis, two large calculi in the left pelvic ureter were not removed. The upper of these two calculi finally found its way into the bladder after ulcerating into the sigmoid colon and thence into the bladder. The calculi and the residual ureter were removed and the fistulae closed, with a successful outcome.- - - - - - - - - - ranking = 4keywords = calculus (Clic here for more details about this article) |
6/14. Gallstone ileus with two separate biliary-enteric fistulae.A patient with gallstone ileus associated with two separate biliary-enteric fistulae has been reported. The patient had exploratory laparotomy with removal of the gallstone from the distal ileum, repair of the two fistula tracts, and cholecystectomy. The pathology report showed adenocarcinoma of the gallbladder. The patient was discharged 14 days after surgery. It is important to point out that the diagnosis was not suspected prior to surgery, although the patient was elderly with known cholelithiasis, no prior abdominal surgery, and clinical symptoms of bowel obstruction. The plain abdominal film showed a partial small bowel obstruction pattern with a pair of air-fluid levels in the right upper quadrant, no air in the biliary tract, and no visible calculus. When there is a clinical suspicion of gallstone ileus and the plain abdominal film is not diagnostic, there are several modalities available that have been proven to be useful (ie, contrast medium examinations, ultrasound, and hepatobiliary scan).- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
7/14. The role of an indium leukocyte scan in the diagnosis of a pyeloduodenal fistula associated with spontaneous disappearance of a staghorn calculus.The use of a 111indium oxine-leukocyte scan (white cell scan) to establish the diagnosis of a pyeloduodenal fistula is described. The patient had a fistula that was associated with spontaneous disappearance of a large staghorn calculus in the involved kidney. The disappearance of the calculus and the presence of a pyeloduodenal fistula were confirmed at surgical exploration. Although neither an excretory urogram nor a retrograde pyelogram was useful to diagnose the fistula preoperatively a 111indium oxine-leukocyte scan revealed the renal abscess and pyeloduodenal fistula.- - - - - - - - - - ranking = 6keywords = calculus (Clic here for more details about this article) |
8/14. Nephro colo cutaneous fistula: use of CT scan to aid diagnosis.Nephro colo cutaneous fistula is an uncommon complication of calculus disease of the urinary tract. A case is presented in which CT scan was helpful in the diagnosis. The treatment which must be individualized usually consists of nephrectomy and colonic repair via oversewing, exteriorization with secondary closure, or resection with primary anastomosis.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |

10/14. Gallstone ileus resulting in strong intestinal obstruction.Mechanic intestinal obstruction, caused by the passage of biliary calculus from vesicle to intestine, through fistulization, although not frequent, deserve study due to the morbi-mortality rates. incidence in elder people explains the association with chronic degenerative diseases, increasing complexity in terms of therapy decision. literature discusses the need and opportunity for the one or two-phase surgical attack of the cholecyst-enteric fistule, in front of the resolution on the obstructive urgency and makes reference to Gallstone ileus as an exception for strong intestinal obstruction. The more frequent intestinal obstruction observed is when it occurs a Gallstone ileus impacting in terms of ileocecal valve. The authors submit a Gallstone ileus manifestation as causing strong intestinal obstruction, discussing aspects regarding diagnostic and treatment.- - - - - - - - - - ranking = 1keywords = calculus (Clic here for more details about this article) |
