The progression-free survival rate was better after a complete resection and in older patients. Progression-free survival rate was the same after lobectomy or more extensive thyroid procedures, but comparison was confounded by the increased use of total or subtotal thyroidectomy in patients with advanced disease. The risk of permanent hypocalcemia increased when total or subtotal thyroidectomy was done. Thyroid lobectomy alone may be appropriate for patients with small localized lesions while total or subtotal thyroidectomy should be considered for more extensive tumors.

Percutaneous nephrolithotomy presents a therapeutic challenge in children because of the disproportion between the sizes of the instruments and the kidneys. A technique for pediatric nephrolithotomy used on a 2-year-old female child is presented. The patient was born prematurely and developed kidney stones as a complication of furosemide therapy. She failed medical management with hydrochlorothiazide, and the stone did not disintegrate following extracorporeal shockwave lithotripsy (ESWL). A Chiba needle was used to access the renal collecting system percutaneously. Using a guidewire, sequential dilatation was performed to 16F. A 15F Hickman catheter introduction kit was then used, and the sheath was partially peeled away. A 10F pediatric cystoscope and grasper were inserted through the sheath to remove the stones. A 12F catheter was then placed through the sheath; the sheath was peeled away, and the catheter was left indwelling for 48 hours. No complications ensued. A postoperative nephrostogram showed free drainage and absence of residual stones. Utilization of the Hickman peel-away sheath constitutes an excellent alternative nephrolithotomy technique for children with stones unresponsive to more conservative treatment.

The revision of duplex scan-detected vein graft stenosis with surgical or endovascular techniques was associated with an excellent patency rate, including when intervention on alternative vein conduits or treatment of restenosis was necessary. When PTA was selected on the basis of clinical and duplex scan selection criteria, the endovascular treatment of focal vein graft stenosis was effective, durable, and comparable with the surgical revision of more extensive lesions.

Both TIPS and HGPCS reduced portal pressure. Placement of TIPS resulted in more deaths, more rebleeding, and more than twice the treatment failures. Mortality and failure rates promote the application of HGPCS over TIPS.
