Squamous cell carcinoma in exstrophic unreconstructed urinary bladder in an adult.

Bladder exstrophy is rare and associated with an increased incidence of bladder cancer. Unreconstructed bladder extrophy presenting in an adult is very rare as most of the patients undergo repair in childhood. Most of the cancers are adenocarcinomas. We report a rare case of squamous cell carcinoma occurring in exstrophic unreconstructed bladder in a 58-year-old male patient.

Laparoscopic versus open pyeloplasty: comparison of two surgical approaches- a single centre experience of three years.

UPJO causes hydronephrosis and progressive renal impairment may ensue if left uncorrected. Open pyeloplasty remains the standard against which new technique must be compared. We analyzed the comparison of Laparoscopic and open pyeloplasty in a randomized prospective trial. A prospective randomized study was done from January 2004 to January 2007 in which a total of 28 Laparoscopic and 34 open pyeloplasty were done. All laparoscopic pyeloplasties were performed transperitoneally. Standard open Anderson Hynes pyeloplasty, spiral flap or VY plasty was done depending on anatomic consideration. Patients were followed with DTPA scan at 3 months and IVP at 6 months. Perioperative parameters including operative time, analgesic use, hospital stay, and complication and success rates were compared. Mean total operative time with stent placement in LP group was 244.2 min (188-300 min) compared to 122 min (100-140 min) in open group. Compared to open pyeloplasty the post operative diclofenac requirement was significantly less in LP group (mean107.14 mg) and open group required mean of (682.35 mg) The duration of analgesic requirement was also significantly less in LP group. The post operative hospital stay in LP was mean 8.29 days (7-11) and was significantly less than open group (mean 3.14 Days (2-7 days). Open pyeloplasty has been the gold standard for UPJO repair and achieves success rates exceeding 90%. Laparoscopic pyeloplasty provides a minimally invasive alternative to repair UPJO and has developed world wide as the first minimally option to match success rate of open pyeloplasty. Its potential advantages including less post op pain, shorter hospital stay an improved cosmesis has been proved in some comparative series. The only disadvantage seems to be longer operative time. LP has a minimal level of morbidity and short hospital stay compared to open approach Although Laparoscopic pyeloplasty has the disadvantages of longer operative time and requires significant skill of intracorporeal knotting but it is here to stay and represents an emerging standard of care.

Transplant ureter should be stented routinely.

Vesicoureteric complications present early after transplantation and contribute to patient morbidity, graft loss and mortality. Ureteral stenting provides a decrease in ureteroneocystostomy anastomotic complications following renal transplantation. There should be prophylactic stent insertion with endoscopic removal at a designated time post transplantation. With the addition of antibiotic prophylaxis post transplantation, ureteric stenting does not increase the rate of urinary tact infections. There is no significant increase in cost for stenting during transplantation in comparison to management of major ureteric complications. Routine stenting causes significant cost-saving per year and prevents anastomotic complications. It is wise to stent the transplant ureter routinely.

Plasmacytoma of the kidney.

Extramedullary plasmacytoma is a rare malignant neoplasm typically arising outside the bone marrow of patients who show no clinical evidence of multiple myeloma. Kidney is a rare site for plasmacytoma. We present here a case of primary renal plasmacytoma confirmed on histopathology of the specimen and immuno-histochemistry studies. Patient was treated with radical nephrectomy followed by radiotherapy. The case is presented due to its rarity.

Xanthogranulomatous pyelonephritis in a horse-shoe kidney.

Xanthogranulomatous pyelonephritis (XGPN) represents an unusual suppurative granulomatous reaction to chronic infection, often in the presence of chronic obstruction from a calculus. We present a case of XGPN in a horse shoe kidney in an adult. Hemi-nephrectomy of the involved side was followed by clinical improvement. The case highlights the importance of early hemi-nephrectomy in XPGN with horse shoe kidney.

Emphysematous pyelonephritis - case report and evaluation of radiological features.

Emphysematous pyelonephritis (EPN) is an acute necrotizing parenchymal and peri-renal infection caused by gas-forming uropathogens. The predisposing factors are diabetes mellitus and ureteric obstruction. E. coli is the most frequently identified pathogen. The overall mortality is 43%. Computerized tomography (CT) is the imaging procedure of choice in determining the extent of infection and guiding management. Management of EPN has evolved from aggressive surgical intervention to conservative management. Although there are reports of improved renal function after medical therapy combined with relief of obstruction, most of the patients still require nephrectomy. We present a case of EPN and also evaluate the radiological features, prognosis, and current management of this disease.

Primary hydatid cyst of kidney and ureter with gross hydatiduria: A case report and evaluation of radiological features.

We report a rare case of echinococcosis, primarily involving the right kidney and ureter, presenting with gross hydatiduria. We also present the salient diagnostic features of renal hydatid.

Laparoscopic versus open pyeloplasty: Comparison of two surgical approaches -- a single centre experience of three years.

BACKGROUND: Ureteropelvic junction obstruction (UPJO) causes hydronephrosis and progressive renal impairment may ensue if left uncorrected. Open pyeloplasty remains the standard against which new technique must be compared. We compared laparoscopic (LP) and open pyeloplasty (OP) in a randomized prospective trial. MATERIALS AND METHODS: A prospective randomized study was done from January 2004 to January 2007 in which a total of 28 laparoscopic and 34 open pyeloplasty were done. All laparoscopic pyeloplasties were performed transperitoneally. Standard open Anderson Hynes pyeloplasty, spiral flap or VY plasty was done depending on anatomic consideration. Patients were followed with DTPA scan at three months and IVP at six months. Perioperative parameters including operative time, analgesic use, hospital stay, and complication and success rates were compared. RESULTS: Mean total operative time with stent placement in LP group was 244.2 min (188-300 min) compared to 122 min (100-140 min) in OP group. Compared to OP group, the post operative diclofenac requirement was significantly less in LP group (mean 107.14 mg) and OP group required mean of (682.35 mg). The duration of analgesic requirement was also significantly less in LP group. The postoperative hospital stay in LP was mean 3.14 Days (2-7 days) significantly less than the open group mean of 8.29 days (7-11 days). CONCLUSION: LP has a minimal level of morbidity and short hospital stay compared to open approach. Although, laparoscopic pyeloplasty has the disadvantages of longer operative time and requires significant skill of intracorporeal knotting but it is here to stay and represents an emerging standard of care.
