Crohn's disease was the topic of a meeting of gastroenterologists in Bergen last year with the purpose of working out consensus guidelines for diagnosis and treatment of this chronic disease. The most important diagnostic procedures are radiology, gastrointestinal endoscopy and histopathology. Transmural, segmental involvement is characteristic, whereas granulomas are found in only 25% of biopsy specimens. Corticosteroids are effective in active Crohn's disease located to all parts of the intestine, whereas sulfasalazine and metronidazole are most effective in Crohn's colitis. Azathioprine and 6-mercaptopurine should be reserved for patients with chronic active disease that is unresponsive to steroids or requires higher doses. Azathioprine also has a prophylactic effect. Surgery is indicated in patients whose quality of life is diminished in spite of adequate medical treatment, in patients with bowel or ureter stenosis, fistula or abscess, and in patients with acute perforation or toxic dilatation. Limited resection is recommended, and stricture plasty can be alternative to extensive resection.

Congenital nephrogenic diabetes insipidus (NDI) is a chronic disorder involving polyuria and polydipsia that results from unresponsiveness of the renal collecting ducts to the antidiuretic hormone vasopressin. Either of the genetic defects in vasopressin V2 receptor or the water channel aquaporin 2 (AQP2) cause the disease, which interfere the water reabsorption at the epithelium of the collecting duct. An unconscious state including a perioperative situation can be life threatening because of the difficulty to regulate their water balance. The Sendai virus (SeV) vector system deleting fusion protein (F) gene (SeV/DeltaF) is considered most suitable because of the short replication cycle and nontransmissible character. An animal model for NDI with reduced AQP2 by lithium chloride was used to develop the therapy. When the SeV/DeltaF vector carrying a human AQP2 gene (AQP2-SeV/DeltaF) was administered retrogradely via ureter to renal pelvis, AQP2 was expressed in the renal collecting duct to reduce urine output and water intake by up to 40%. In combination with the retorograde administration to pelvis, this system could be the cornerstone for the applicable therapies on not only NDI patients but also other diseases associate with the medullary collecting duct.

Bladder pain syndrome/interstitial cystitis (BPS/IC) is a chronic disease characterized by pelvic pain urgency and frequency. Patients with severe symptoms lead a very miserable life. North American, European and Asian guidelines have been recently promulgated but they differ on many important issues. There is no consensus on its name, definition, investigations and management. Indian guidelines have also been developed and they give more importance to the symptoms in relation to micturition. Though initially believed to be rare or non-existent in India the situation has changed. In Indian patients the presentation is more or less same as the rest of the world but a large percentage have obstructive symptoms and unusual urinary symptoms. Anal discomfort is also common. In India the commonest investigation in all cases of lower urinary tract (LUT) dysfunction is ultrasonography of kidney ureter and bladder with measurement of the post void residual urine volume. Cystoscopy is also done in all the cases to rule out presence of tuberculosis or carcinoma in situ. Bladder pain syndrome/interstitial cystitis (BPS/IC) is not considered to be a clinical disease as it is difficult to rule out all differential diagnosis only from history. Hunner's lesion is very rare. Cystoscopy with hydro distension, oral therapy, intravesical therapy and surgical therapy form the back bone of management. It is difficult to know which treatment is best for a given patient. A staged protocol is followed and all the treatment modalities are applied to the patients in a sequential fashion-starting from the non-invasive to more invasive. Intravesical botox has not been found to be effective and there is no experience with interstim neuromodulation.

As the field of transplant evolves and patients with chronic disease live longer, retransplant for end-stage renal disease becomes more common because kidney allografts have a limited lifespan. In renal retransplant, graft and patient survival is near equivalent to first-time transplant; however, these procedures present a unique surgical risk profile, especially third and subsequent transplants, which are reviewed in this manuscript. The risk of bowel obstruction in primary kidney transplant recipients is much lower than patients who have undergone laparotomy for second or third transplant because of the retroperitoneal location of the transplanted kidney. Internal hernia is an uncommon cause of small bowel obstruction, particularly after kidney transplant, and often diagnosis and intervention are delayed because of diagnostic uncertainty. We report a case of a 34-year-old man with acute kidney injury and bowel obstruction, whose final diagnosis was an internal hernia around the transplanted ureter of an intra-abdominally placed third renal transplant resulting in ureteric obstruction associated with small bowel obstruction-a case of double obstruction.
