Dual-tracer PET/CT in renal angiomyolipoma and subtypes of renal cell carcinoma.

Unlabelled: We studied the metabolic characteristics of RCC subtypes and angiomyolipoma with 18F-FDG and 11C-acetate PET/CT.

Methods: Fifty-eight patients with both baseline CT and dual-tracer PET/CT were recruited: 10 angiomyolipoma (16 lesions) and 48 RCC (50 lesions). Each lesion was assessed for SUVmax ratio (lesion-to-normal kidney) on 11C-acetate/18F-FDG PET and attenuation density on CT.

Altered expression of aquaporin-2 in human explants with chronic renal allograft dysfunction.

Objective: To investigate the distribution of aquaporins, a recently discovered family of transmembrane water channels, in human renal explants, with specific reference to chronic renal allograft dysfunction (CRAD).

Materials And Methods: Immunohistochemistry for aquaporin-1 and -2 was used in 11 explants, of which five had clinically and histologically confirmed CRAD. Controls were taken from the six explants unaffected by CRAD and from histologically normal areas of six kidneys excised for renal tumours.

Impact of previous surgery on endoscopic extraperitoneal radical prostatectomy.

Objectives: To assess the impact of previous surgery on endoscopic extraperitoneal radical prostatectomy (EERPE).

Methods: A total of 500 patients who underwent EERPE for clinically localized prostate cancer between December 2001 and April 2004 were stratified into five groups: group 1, no previous abdominal, inguinal, or prostate surgery; group 2, previous upper abdominal surgery; group 3a, previous lower abdominal or pelvic surgery or open inguinal hernioplasty; group 3b, laparoscopic or endoscopic inguinal hernioplasty; group 4, previous prostate surgery; and group 5, a combination of groups 2, 3, and/or 4. Groups 1 and 2 were analyzed together, because the previous operative fields in group 2 were distant from the space of Retzius.

Parastomal hernia repair using the lateral approach.

Objective: To review the results of repairing a parastomal hernia after ileal conduit formation, using the lateral approach.

Patients And Methods: We retrospectively assessed 18 patients (9%) who developed a parastomal hernia, from 211 who had an ileal conduit created between 1982 and 2001; 15 had a surgical repair using a lateral incision.

Results: All 15 patients resumed a normal diet 1 day after surgery; the median (range) hospital stay was 4 (2-14) days.
