7. 5. Penile carcinoma : from first symptom to sexual function and life satisfaction following organ-sparing laser treatment

   Författare :Elisabet [Elisabeth] Skeppner; Jan-Erik Johansson; Torgny Windahl; Kerstin Sjögren Fugl-Meyer; Hans Hedelin; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Penile carcinoma; sexuality; life satisfaction; treatment-seeking; sexual function; Sexual dysfunction; delay; organ-sparing; Surgery; Kirurgi;

   Sammanfattning : The overall aim of this thesis was to describe how patients with penile carcinoma experienced their symptoms, treatment seeking and the impact of the diagnosis and treatment on sexual function, sexual activity and life satisfaction. The thesis contains two studies of patients treated with organ-sparing laser therapy, a retrospective study (Papers II and III) of 46 patients treated between 1986-2000 and a prospective study (Papers I and IV) of 50 patients between 2005 and 2009 and additional 34 partners.
