The necessity for preoperative ureteral catheter insertion for colorectal operations continues to be controversial. To determine our experience and what complications might be associated with ureteral catheter use, the charts of all patients in our department undergoing ureteral catheterization in combination with colorectal procedures between the years 1978 and 1989 were reviewed. The indications for operation, the presence or absence of urinary tract symptoms, and intravenous pyelogram findings (if performed) were recorded. Time for the procedure, size and number of catheters, and complications were noted. From the operative report, a retrospective grading of necessity for ureteral catheterization was assessed according to a scale from A to D. There were 120 ureteral catheterizations performed, bilaterally in 60 per cent of cases. Complications included renal colic (1), oliguria (1), and anuria (2). Intraoperatively, one ureter was cut and one ureter tied but recognized by palpation and ligature removed. Retrospective grading deemed ureteral catheterization necessary in 27.5 per cent of cases. We conclude that catheters are helpful in selected cases. For patients with bilateral catheter insertion, complications can be reduced by ensuring urine output prior to removal of the second catheter.

Kidney stones are common in industrialised nations: up to 15% of white men and 6% of all women will develop one stone, with recurrence in about half these people. Risk factors for formation of stones include urinary promoters (calcium, urate, cystine, and sodium) and urinary inhibitors (magnesium, citrate, and nephrocalcin). Acute renal colic can be precipitated by dehydration and reduced urine output, increased protein intake, heavy physical exercise, and various medicines. Such colic manifests as severe loin pain and can be accompanied by frequent urination, dysuria, oliguria, and haematuria. Documentation of stone characteristics is extremely important: type, size, location, and underlying metabolic abnormalities. Such details can be obtained with a combination of biochemical investigations, microscopic examination of urine under polarised light, and an intravenous pyelogram. Ultrasonography and plain abdominal radiographs are also useful, especially for patients unable to tolerate an intravenous pyelogram. Acute therapy includes complete pain relief, rehydration, and encouragement of diuresis. Long-term management encompasses education of patients with regard to diet and fluid intake, control of calciuria, citrate replacement, and treatment of any underlying urinary-tract infection or metabolic abnormality. Stones smaller than 5 mm normally pass spontaneously, whereas larger stones, as big as 2 cm, are best treated with extracorporeal shock-wave lithotripsy. All physicians should have a clear understanding of the pathogenesis and clinical management (acute treatment and prevention of recurrence) of renal stone disease.

A 70-year-old man with clinically localised prostate carcinoma underwent extraperitoneal endoscopic radical prostatectomy. His medical history revealed hypertension, renal colic, hypogonadotropic hypogonadism and recurrent deep venous thrombosis in the legs. The operation was uneventful with 500 ml blood loss and no periods ofhypotension. The patient developed oliguria within 12 h after surgery. A hypovolemic state was initially suggested to explain the oliguria and increasing amounts of intravenous fluids were administered. The oliguria persisted, however, and the patient did not respond to a diuretic. There was no fluid loss in the drain. Blood pressure, pulse and temperature were normal. Peritonitis and bowel perforation were excluded. Ultrasound examination of the bladder and kidneys revealed an empty bladder and no dilatation of the upper urinary tract, which excluded a post-renal obstruction. The clinical situation deteriorated within hours as the patient developed anuria, bowel distension, metabolic acidosis with progressive renal failure and signs of respiratory distress for which mechanical ventilation was needed. A chest X-ray prior to intubation did not show pneumonia or signs indicating pulmonary embolism. CT of the abdomen was performed to evaluate urinary leakage but revealed no fluid collection or urinoma. Thus pre- and post-renal causes of oliguria were excluded. In view of the systemic symptoms, intra-abdominal pressure was measured using a bladder catheter; it varied between 25 and 35 cm water. Together with the clinical situation, a diagnosis of abdominal compartment syndrome was made and coeliotomy was performed immediately. Within 10 min after decompression of the peritoneal cavity, diuresis started spontaneously. Renal function was restored to preoperative levels in 3 weeks. Abdominal compartment syndrome is a potentially life-threatening cause of anuria. The syndrome should be part of the differential diagnosis for patients with postoperative anuria, including those who underwent extraperitoneal minimally invasive procedures.

Legionnaires' disease (LD) is an often overlooked but a possible cause of sporadic community acquired pneumonia. High fever, cough and gastrointestinal symptoms are non-specific symptoms. Hyponatremia is more common in LD than pneumonia linked with other causes. A definitive diagnosis is usually confirmed by culture, urinary antigen testing for Legionella species. Macolide or quinolone antibiotic is the treatment of choice. We describe a case of Legionella pneumonia presenting with high fever, bilateral flank pain and oliguria. It is important for clinicians to be aware of this diagnosis when managing patients with flank pain. The case highlights the problems in differentiating LD from renal colic and the importance of proper history, physical examination with laboratory tests for appropriate management.

Pleural effusions due to pleural injury following supracostal percutaneous nephrolithotomy (PCNL) occur in upwards of 15% of patients; however, these effusions are invariably diagnosed immediately postoperative or during the hospital stay. Herein, we report our initial experience with a delayed nephropleural fistula. A 52-year-old female underwent an uneventful supracostal right PCNL staghorn stone procedure and was discharged on postoperative day 1. She presented to the emergency department 8 days after her original procedure and one day after ureteral stent removal in the office, with right pleural effusion, concomitant contralateral renal colic secondary to migration of a left pelvic stone into her left proximal ureter, and acute renal failure/oliguria. She was treated with right chest tube drainage, bilateral nephrostomy tube placement, and subsequent left holmium laser ureterolithotripsy.
