Bilateral subcutaneous pyelovesical bypass in a Hautmann neobladder followed by a mononeuropathy multiplex and an underlying polyarteritis nodosa diagnosis.

Subcutaneous pyelovesical bypasses are the best choice for the long-term palliative treatment of ureteral obstructions. In rare cases this obstruction is due to polyarteritis nodosa. We present the only reported patient with a bilateral Detour bypass in a Hautmann's neobladder. The patient also suffers from polyarteritis nodosa.
