Laparoscopic pyelolithotomy.

Laparoscopic surgery has been applied to virtually every aspect of urinary tract disease. Presented is a case of laparoscopic-extended pyelolithotomy accomplished in a 16-month-old child with a large cystine stone that occupied the child's entire renal pelvis. Although not the first pyelolithotomy accomplished laparoscopically, we believe this to be the first extended laparoscopic pyelolithotomy and also believe this is the youngest patient in whom laparoscopic pyelolithotomy has been done. Extracorporeal shock wave lithotripsy and percutaneous and endoscopic stone techniques have drastically modified the management of urolithiasis. However, select cases in which these techniques may not be applicable (such as this toddler with bulky cystine lithiasis) may require open surgery. The laparoscopic approach represents an excellent, yet less-invasive option.

Premalignant lesions and nonsquamous malignancy of the penis and carcinoma of the scrotum.

Premalignant lesions of the penis include cutaneous horn, balanitis xerotica obliterans, and leukoplakia. The true incidence of progression of each of these to squamous-cell carcinoma is unknown. Bowenoid papulosis, erythroplasia of Queyrat, and Bowen's disease are histologically identical to in situ carcinoma. Although the first is consistently benign, the latter two regularly evolve into invasive cancer. Malignant scrotal lesions include squamous-cell carcinoma, liposarcoma, leiomyosarcoma, basal-cell carcinoma, extramammary Paget's disease, erythroplasia of Queyrat, malignant melanoma, and metastases. Hemangioma can be confused with carcinoma.

The adrenal gland and renal cell carcinoma: is ipsilateral adrenalectomy a necessary component of radical nephrectomy?

The ipsilateral adrenal gland may be involved by renal cell carcinoma through direct invasion or embolic metastases, and usually it is removed as part of the radical nephrectomy specimen. We reviewed retrospectively 44 patients with stage A and 8 patients with stage B renal cell carcinoma, 25 of whom had undergone ipsilateral adrenalectomy. The 5-year and 9-year survival of these 25 patients was 79 and 65 per cent, respectively, and was not statistically different from the 78 per cent 5-year and 9-year survival of those 27 patients who did not undergo ipsilateral adrenalectomy. These findings suggest that the ipsilateral adrenal gland need not be removed routinely as part of perifascial nephrectomy for renal cell carcinoma. Those patients who are found to have a contralateral adrenal lesion during preoperative evaluation should be spared bilateral adrenalectomy if there is no ipsilateral adrenal gland involvement at exploration. Those patients with lower pole lesions also need not undergo routine ipsilateral adrenalectomy. Preoperative computerized tomography scans will help to select those tumors that can be managed by perifascial nephrectomy with sparing of the ipsilateral adrenal gland.

Cancer serum index and prostatic acid phosphatase for detection of progressive prostatic cancer.

The ratio of alpha 1 acid glycoprotein/prealbumin, referred to as a cancer serum index, has been proposed as a marker for neoplastic disease. In a series of 130 patients with prostate cancer, the cancer serum index was measured along with serum prostatic acid phosphatase. A significant difference for both the cancer serum index and serum prostatic acid phosphatase was detected between those patients with no evidence of active disease after treatment and those with progressive disease after treatment.

Four cases of metastases to the penis and a review of the literature.

Penile metastases are rare and usually are secondary to other genitourinary primaries. Approximately 200 cases have been reported. Survival for more than 1 year is unusual, and multiple metastases have been present in all autopsied cases. Occasional survival longer than 5 years has occurred with surgical excision, suggesting the possibility of cure for those patients in whom control of the primary has been achieved and who show no other clinical metastatic lesions.

Solitary lesions on bone scan in genitourinary malignancy.

Solitary lesions on bone scans obtained as part of metastatic diagnostic studies for genitourinary malignancy require identification as to whether they represent nonneoplastic or neoplastic disease and, if neoplastic, whether metastatic genitourinary cancer or another primary is present. Such definition requires at least plain film tomograms of the area as well as computerized tomography (for inaccessible lesions) and/or biopsy of lesions still in doubt after tomography. Of the 9 patients in our study 4 had true positive scans for metastatic disease, 3 had false positive scans, 1 had a true positive scan for a second bone primary and 1 is indeterminate, since a negative biopsy of a positive area on a bone scan was followed rapidly by the appearance of other widespread metastases.
