Ileocaecocystoplasty was performed after subtotal cystectomy in a man with extensive leukoplakia of the bladder as a prophylaxis against carcinoma. 2 years later the ureter (contralateral nephrectomy had previously been performed) became blocked by an unusual interstitial inflammation complicated by necrosis and calcification. This was excised, and the tail of the ileum anastomosed to the renal pelvis with a good result at 20 months.

We herein describe 44 new cases of leukoplakia of the renal pelvis, bladder and urethra. Leukoplakia is uncommon. It occurs twice as often in the bladder as in the pelvis and ureter and it is associated with and perhaps caused by chronic infection. Carcinoma is present in 10 to 20 per cent of the cases at diagnosis. We believe that leukoplakia is not simple squamous metaplasia but a step further down the line--a process that evolved through squamous metaplasia and perhaps could result in cancer. We think leukoplakia is potentially pre-malignant and it should be treated as a low grade and low stage tumor since no satisfactory treatment exists.

A case of hyperkeratotic squamous epithelium of the distal renal pelvis and ureter, clinically identifiable as leukoplakia, is reported in a solitary kidney. Because of the need to conserve renal parenchyma in this patient, the lesion was treated conservatively at operation after careful exploration and full thickness biopsy failed to reveal malignancy. Close monitoring of this potentially premalignant lesion has documented no progression at twenty-five months.

We are presenting a case of leukoplakia spread to the bilateral renal pelvis, ureter and bladder in a 52-year-old woman. We believe this case is important because it involves leukoplakia that is more extensive than in any cases previously cited in the literature. No other possible etiologic cause except a heavy smoking habit was defined. Conservative follow-up was preferred to aggressive surgery.
