Giant intra-adrenal myelolipoma associated with recurrent urinary tract infection.

Adrenal myelolipomas are rare benign tumours that may be identified on routine imaging studies. The association of myelolipomas with obesity, hypertension and malignant tumours has been reported. We describe a giant intra-adrenal myelolipoma in a 40-year-old woman that is the largest asymptomatic tumour of this type documented in the past 10 years. To avoid unnecessary and extensive treatment, the distinction of benign from malignant adrenal tumours or extra-medullary haematopoietic tumour is important, particularly when a small, inactive adrenal mass is found incidentally.

Bladder stone causing renal failure.

We describe a 62-year-old man with a large bladder calculus causing bilateral ureteral obstruction. Diagnosis was delayed despite the patient's history of recurrent urinary infections. This case report illustrates the importance of radiological evaluation of patients presenting with recurrent urinary infections. To our knowledge, only three previous reports of bladder stone causing renal failure have been published.

Urinary calculi during pregnancy. When are they cause for concern?

Urolithiasis during pregnancy, though rare, can be challenging both diagnostically and therapeutically. It is helpful if the physician is quick to suspect the presence of stones in the presence of appropriate signs and symptoms, particularly flank pain and tenderness, hematuria, or unresolved bacteriuria. Ultrasonography is the diagnostic imaging method of choice, but modified intravenous urography should be performed whenever this study is necessary for a prompt diagnosis. In the absence of sepsis, renal failure, or intractable pain, conservative management with hydration, analgesics, and (if infection is present) antibiotics is the favored initial approach. If conservative management fails, stent insertion or placement of a percutaneous nephrostomy tube may be appropriate. Ureteroscopy with stone manipulation for distal ureteral stones during pregnancy has also been reported in some cases. If these methods fail, open surgery should be used for stone removal.
