Renal colic in pregnant patients can be complicated by pyelonephritis and premature labor, especially if misdiagnosed or inadequately treated. Ultrasound is a safe and sensitive diagnostic test. Approximately two-thirds of renal calculi will pass spontaneously. For those who require intervention, placement of a Double-J stent is a safe and effective option.

We report 6 cases of renal angiomyolipomas and review the pertinent literature concerning this disease. One case involved the rare association of tuberous sclerosis and pregnancy. Another patient without tuberous sclerosis had renal cell carcinoma and later suffered a contralateral angiomyolipoma. The pathological conditions of renal angiomyolipomas with and without tuberous sclerosis are discussed. Since angiomyolipomas present with multiple clinical similarities to renal cell carcinoma, the primary task for the clinician is to differentiate this hamartoma from carcinoma. The distinguishing characteristics and the clinical management of renal angiomyolipomas are discussed.

Of 43 testicular tumors in children seen at the Children's Hospital Medical Center and Sidney Farber Cancer Institute 33 were malignant. These tumors occurred primarily in young children. Any solid scrotal mass in an infant must be considered malignant until proved otherwise. Primary emphasis is placed on the 20 cases of embryonal cell carcinoma. Of 9 patients who underwent only orchiectomy 5 have died, whereas all 11 patients who received combination therapy have survived. We recommend radical inguinal orchiectomy, extended unilateral retroperitoneal lymphadenectomy and adjuvant chemotherapy in repeated courses for 2 years. Radiotherapy is withheld if the lymphadenectomy is negative.
