This article takes into account the diagnostic reliability of ultrasounds (US) in the ureteral lithiasis localisation. A stone has been ultrasonographically localised in 82.3% of 119 patients, this rate rising up to 89.4% in the last 85 consecutive patients. From a clinical point of view, 104 patients presented renal signs, whereas 10 out of them showed an atypical symptomatology, which at first led to a suspicion of acute appendicitis (5), intestinal obstruction (4), acute pancreatitis (1). A stone was accidentally detected in five asymptomatic patients. In 80% of the cases, the stone was situated in the proximal or juxtavesical ureter; in 20%, in the middle or distal ureter. A particular stress is laid in the ultrasonographic follow-up, by which the stone was uncovered in 6 cases, at first considered negative at US. Eight patients had to be referred to treatment with ESWL.

1. Widespread visceral and intestinal wall metastases are present in women dying with ovarian cancer. Intestinal wall invasion is commonly found at autopsy and is associated with bowel obstruction. Liver parenchymal replacement by metastases in more extensive than that in the lung, where most metastases have a subpleural location. Multifocality characterizes metastases in both of these organs. 2. Neoplastic lymphatic invasion is common. Lymphatic and blood vascular invasion are associated with an increased incidence of metastases in lymph nodes, small bowel wall, pancreas, lungs, ureter, and liver. 3. The mean survival time from diagnosis to death is less than 2 years. Both increasing neoplastic histological grade and clinical stage at diagnosis are associated with decreased survival time. 4. The most common causes of death are carcinomatosis, infection, or a combination of these processes. Sepsis, pneumonia, or both of these account for most of the fatal infections. 5. Bowel and ureteral obstruction constitute the most common forms of tumor-induced morbidity. The former process tends to be multifocal, involving the small and large intestines, and it is found during the disease course as well as at autopsy. Ureteral involvement is usually associated with hydronephrosis and is bilateral in approximately one fourth of the cases.

Two cases of carcinoma in a diverticulum of the bladder were experienced. The first case was of a 50-year-old male who presented in February, 1981, complaining of asymptomatic microhematuria. The excretory urogram revealed a diverticulum in the left lateral aspect of the bladder which was causing shift of the lower ureter to the median side. The cytology report of voided urine was class III. Diverticulectomy was performed and pathologic findings was a transitional cell carcinoma, grade 1, stage 0. The patient has been free of recurrence for the past 54 months. The second case was of a 67-year-old male with the chief complaint of pollakiuria. Non-papillary tumor in a diverticulum of the bladder was found by cystoscopy and computed tomography. Tumor biopsy and urinary diversion by ileal conduit were performed in the usual manner. The pathologic finding was transitional cell carcinoma of grade 11 malignancy. The patient died of intestinal obstruction on January, 19, 1984, about 15 months after the surgery. The 117 cases of carcinoma in a diverticulum of the bladder we found in the Japanese literature are reviewed briefly.

Clinical and morphologic factors that affected the distribution of disease are described in 100 cases of ovarian cancer at autopsy. In addition to the expected pattern of pelvic and abdominal peritoneal spread, extensive visceral parenchymal metastases were seen: liver parenchyma (45%), lung parenchyma (39%), small and large intestinal wall (52% and 55%), lymph nodes (70%), pancreas (21%), ureter (24%), bone (11%), and brain (6%). Liver parenchymal metastases replaced more than one third of the liver in 25% of cases, whereas lung metastases always involved less than one third of the lungs. When intestinal wall invasion was seen, bowel obstruction was present more often (71%) than when only intestinal serosa was involved (30%). Lymphatic invasion was predictive of lymph node, small intestinal wall, pancreatic, and liver as well as lung parenchymal metastases. Blood vessel invasion was predictive of pancreatic and ureteral metastases. Clinical stage I at diagnosis was associated with high incidences of liver parenchymal (56%), lymph node (56%), lung parenchymal (44%), large intestinal wall (33%), and bone (33%) metastases. Thus, ovarian cancer has parenchymal metastases similar to other carcinomas in addition to its peritoneal spread. Lymphatic and blood vessel invasion is predictive of such involvement. Intestinal wall invasion predicts bowel obstruction.

This is a survey of 234 pediatric patients in whom staging laparotomy/splenectomy was carried out (1975 to 1981) in the course of the Intergroup Hodgkin's Disease in Childhood Study (IHDCS). Relapse has occurred in 44 of these patients, and 12 have died, 7 secondary to extension of lymphoma, 2 with herpes or pneumocystis infections, 2 with leukemia, and 1 from an unrelated accident. During the period of surveillance (mean 5.5 yr), five episodes of bacterial sepsis (positive blood cultures) have occurred, including two due to Streptococcus pneumoniae; and three, to Hemophilus influenzae. The former occurred in the small group of patients in this series who had not received the prescribed pneumococcal vaccination. No fatalities were associated with these septic episodes. Intestinal obstruction secondary to adhesions (benign) occurred in eight patients and was managed without intestinal resection or mortality. One patient required operative release of an obstructed ureter following laparotomy, and one, oophorectomy for an infarcted (transposed) ovary.

The ectopy of the ureter orifices and ureterocele are always followed by either mechanical or dynamic obstruction of the ureter and obstructive pyelonephritis. These anomalies are periodically accompanied by abdominal pains which make their appearance during an attack of acute pyelonephritis. These abdominal pains can be erroneously taken for symptoms of appendicitis or intestinal obstruction and the patients are subjected to appendectomy or laparotomy by mistake. The erroneous appendectomy or laparotomy were fulfilled in 47 of 201 patients with ectopy of ureter orifices and ectopic ureterocele which were observed by the authors. The differentiation of genesis of abdominal pains may be more exact with the help of chromocystoscopy, excretory urography and isotopic renography.

Contribution of one case of urachal cyst in a patient initially diagnosed with intestinal obstruction due to a probable colon-sigma neoplasia. The patient underwent discharge colostomy after finding an extension of the likely tumour to abdominal wall, bladder and right ureter. Later, the patient was reassessed and the CT showed a mass in the bladder's anterior edge with disclosure of purulent material and inflammatory cytology through the PAAF. The treatment performed was partial cystectomy, closure of colostomy and rectum-sigma re-anastomosis. Histological diagnosis was urachal cyst, abscess and pyogenic membranes, with no evidence of tumoral tissue. The idiosyncrasy of this urachal cyst is the simulation of an intestinal obstructive process of tumoral origin. Differential diagnosis in these intestinal processes rarely includes urachal cyst.

Idiopathic retroperitoneal fibrosis is uncommon in pregnancy. We have described the case of a pregnant patient with a benign retroperitoneal spindle cell tumor involving the distal duodenum, right ureter, and right iliac artery and vein. She was treated with a left ureteral stent and a right percutaneous nephrostomy. Ultimate cause of death was electrolyte imbalance due to bowel obstruction.

Chronic intestinal pseudo-obstruction denotes the clinical picture that results due to the failure of intestinal peristalsis to overcome the normal resistance to flow and is characterized by recurrent episodes of signs and symptoms of intestinal obstruction in the absence of any mechanical compromise of the intestinal lumen. The region(s) of the gut affected may be isolated or diffuse. It is not uncommon to find evidence of autonomic neuropathy and smooth muscle dysfunction with extraintestinal manifestations such as urinary symptoms from abnormal ureter or bladder function. Intestinal pseudo-obstruction can be caused by a variety of diseases, and for simplicity, certain authors have divided it into myopathic and neuropathic categories. Intestinal pseudo-obstruction may present at any age with a variable amount of abdominal pain, distension, nausea, diarrhea, or constipation and with laboratory abnormalities usually reflecting the degree of malabsorption and malnutrition present. The radiologic findings are varied but commonly include paralytic ileus or signs of apparent clinical obstruction with dilated loops of bowel. The number of pseudo-obstruction cases is dependent on how one defines the condition. It appears prudent to require radiographic abnormalities consistent with obstruction on a plain film of the abdomen for the diagnosis. More recently, studies have focused on the gastrointestinal manometric abnormalities of the stomach and small intestine in chronic intestinal pseudo-obstruction during fasting and fed states; however, sensitivity and specificity of these abnormalities are not well defined. Treatment is aimed at limiting symptoms and maintaining adequate nutrition. Prokinetic agents should be tried in an attempt to restore normal intestinal propulsion. However, their overall efficacy appears to be variable. It is still too premature to consider intestinal pacing or small bowel transplantation in this condition. Surgical approaches to chronic intestinal pseudo-obstruction should be limited to patients refractory to medical therapy, and even then, an approach focused on the patient's primary presenting symptoms should be considered.

The overall frequency of ureteral injury during laparoscopic adnexectomy for endometriosis is unknown, and intestinal obstruction after laparoscopy is rare. Our patient had two postoperative complications: small bowel obstruction and bilateral ureteral injuries discovered 2 and 39 days, respectively, after outpatient laparoscopic adhesiolysis and bilateral salpingo-oophorectomy for severe endometriosis. Pelvic examination and vaginal sonography revealed a large unilocular cystic mass. Laparoscopy showed a fixed large endometrioma firmly attached to pelvic peritoneum and intestines in the pelvic cavity, and significant adhesions in the upper part of a midline incision from prior abdominal hysterectomy. These midabdominal adhesions were not released. The patient underwent laparoscopic bilateral adnexectomy as an outpatient. Two days later she was admitted with small bowel obstruction. Thirty-nine days later, diagnostic evaluation revealed urinary ascites with right ureteral stricture at the uterine artery level, and complete ligation and resection of the left ureter at the pelvic brim near the infundibulopelvic ligament stump. She underwent left ureteral implantation with psoas hitch and right ureterolysis. Follow-up cystogram and intravenous pyelography at 6 and 20 weeks revealed complete recovery. In cases of severe endometriosis with significant ureteral and intestinal involvement, laparotomy may have to be considered.
