Small intestine
It is approximately 1.5 cm in diameter in newborns after 35 weeks of gestational age, and 2.5–3 cm (1 inch) in diameter in adults. On abdominal X-rays, the small intestine is considered to be abnormally dilated when the diameter exceeds 3 cm. On CT scans, a diameter of over 2.5 cm is considered abnormally dilated. The surface area of the human small intestinal mucosa, due to enlargement caused by folds, villi and microvilli, averages 30 square meters.
List of kidney stone formers
Kidney stones can reach exceptional size. In December 2003, a kidney stone weighing 356 g (12.5 oz) was removed from the right kidney of Peter Baulman of Australia. At its widest point, the stone measured 11.86 cm (4.66 in). In 2017, a 2 kg (4.4 lb) stone spanning 20 cm was surgically removed from Abdul Abu Al Hajjar in Kensington, England. As of August 2006, the most kidney stones ever passed naturally was 5,704 by Canadian Donald Winfield. The largest number removed through surgery was 728, during a three-hour operation upon Mangilal Jain of India, on January 27, 2004.
Fictional incidents of kidney stones have been portrayed in the media on several occasions.
