BACKGROUND: Lithiasis during pregnancy can be a serious problem representing a danger to both the mother and the fetus. Surgical intervention is needed in approximately one-third of patients reporting pain despite analgesia and/or signs of persistent infection and obstruction, but there is a lack of consensus in the scientific literature as to the use of the most appropriate procedure to treat this condition. CASE PRESENTATION: We describe our experience in the treatment of a complicated reno-ureteral lithiasis in a 27-year-old patient in the first trimester of pregnancy...

A 54-year-old man was introduced to our hospital for follow-up examinations after renal transplantation. At the initial visit, a 25 mm renal transplant stone was noted, which had enlarged to 32 mm at an examination 1 year later. We first attempted transurethral lithotripsy (TUL), but failed due to ureteral stricture. However, we could completely remove the stone in 2 sessions of percutaneous nephrolithotripsy (PNL). The incidence of urinary lithiasis after renal transplantation ranges from 0.17-1.8%, for which PNL and TUL are frequently used...
