Leopold Ritter von Dittel

Leopold Ritter von Dittel (May 29, 1815 – July 28, 1898) was an Austrian urologist born in Fulnek, a community now located in the Czech Republic.

Dittel received his medical doctorate in 1840 from the University of Vienna, and as a young man worked as a physician in Trentschin-Teplitz.

He is credited for developing a number of innovative diagnostic and surgical practices in the field of genitourinary medicine.

He is remembered for his pioneer diagnostic work with the cystoscope, a device that was a recent invention of urologist Maximilian Nitze (1848–1906).

With Felix Legueu (1863–1939) and Émile Forgue (1860–1943), the "Dittel-Forgue-Legueu operation" is named, defined as a surgical procedure for closure of vesicovaginal fistulae (VVF).
