Sinescu has studied abroad: in 1984, urological microsurgery at the University of California, Los Angeles School of Medicine and the University of Louisville School of Medicine (introducing the practice to Romania the following year[3]); in 1989, extracorporeal shock wave lithotripsy (ESWL) and endourology at Hamburg and Munich; in 1990, ESWL in Beijing and Shanghai, and kidney transplantation in Tel Aviv; in 1991-1992, urologic oncology, reconstructive surgery, endourology and kidney transplantation in Paris; in 1993-1994, urologic oncology, reconstructive surgery and kidney transplantation at Louisville, Case Western Reserve University School of Medicine and the Cleveland Clinic; in 1997, kidney transplantation at the University of Cape Town; and in 2005, pancreas transplantation at the University of Minnesota Medical School.
[2] In addition to several specialty treatises, he is the author of over 200 journal articles, monographs, medical films and courses for students.
[4] Since 1997, he has headed the Centre for Urological Surgery, Dialysis and Kidney Transplantation at the Fundeni Clinical Institute.
[7] Sinescu's hold on the prorectoral position came under attack in the summer of 2007, when he was accused of copying entire fragments and drawings from a 1957 American textbook for a work on clinical urology he published in 1998; he denounced the "slanderous" and "cowardly" campaign run against him by Gardianul newspaper, claiming it was the product of doctors opposed to his bid to enter the Academy.
[10] Also in 2007, he drew criticism for the way he handled the prostate operation of the 92-year-old Patriarch of the Romanian Orthodox Church, Teoctist Arăpaşu, following which the latter died.
