Açık radikal retropubik prostatektomi sonrası inflatable penil protez rezervuarı, penoskrotal transvers insizyon ile Retzius alanına güvenle yerleştirilebilir

AMAÇ: Şişirilebilir üç parçalı IPP (3pIPP) rezervuarının rutin uygulamada yerleştirildiği bölge transversalis fasyasının altındaki Retzius alanıdır. Geçirilmiş majör pelvik cerrahiden sonra fibrozis gelişmesi olasılığı, Retzius boşluğuna penil protez rezervuarının yerleştirilmesini zorlaştırabilir. Penoskrotal transvers insizyon ile penil protez rezervuarının Retzius boşluğuna yerleştirilmesi ile ilgili olası komplikasyonları ve güvenlik kaygılarını ele almak amacıyla deneyimlerimizi gözden geçirdik. GEREÇ ve YÖNTEMLER: 2010–2017 yılları arasında transvers skrotal kesi ile 3pIPP implantasyonu yapılan 122 hastanın 39’unda lokalize prostat kanseri (PKa) nedeniyle açık retropubik radikal prostatektomi öyküsü mevcuttu (ARRP grubu). ARRP grubundaki hastaların 7’sine AMS LGX, 18’ine AMS 700 CX ve 14’üne Coloplast TITAN protez, radikal prostatektomi ve pelvik cerrahi öyküsü olmayan Non-ARRP grubu olarak belirlenen 83 olgunun 6’sına AMS LGX, 19’una AMS 700 CX ve 58’ine Coloplast TITAN protez yerleştirildi. Yerel etik kurul onayı alındıktan sonra grupların demografik özellikleri intraoperatif bulguları, postoperatif izlem verileri karşılaştırıldı. BULGULAR: ARRP ve Non-ARRP grubunun yaş ortalamaları sırasıyla 62,2±6,5 yıl ve 58,6±9,5 yıl idi (p=0,06). Sırasıyla ARRP ve Non-ARRP gruplarında ortalama cerrahi süreleri 57,2±11,3 ve 56,7±5,3 dakika (p=0,32); ortalama izleme süreleri ise 58,7±36,9 ve 50,1±27,5 ay idi (p=0,33). Toplam 58 aylık ortalama takip süresince ARRP grubunda birer olguda mekanik bozukluk (%2,6) ve protez enfeksiyonu (%2,6) gelişti. Non-ARRP grubunda ortalama 56 aylık takiplerde bir olguda inguinal herni gelişimine bağlı rezervuar dislokasyonu (%2,6); 3 olguda mekanik bozukluk (%3,6) ve bir olguda ise protez enfeksiyonu (%1,2) gözlendi. İPP implantasyonundan memnuniyet oranları ARRP ve Non-ARRP gruplarında sırasıyla 86,8±11,3 ve 85,8±12,2 idi (p=0,91). SONUÇ: Açık radikal prostatektomi öyküsü olan hastalarda, penoskrotal insizyonla üç parçalı penil protez ve rezervuarı retropubik Retzius boşluğuna düşük komplikasyon oranlarıyla ve yüksek tedavi memnuniyet oranları ile güvenle yerleştirilebilir. Nadiren gerekse de ektopik rezervuar yerleştirilmesi alternatif bir prosedür olarak akılda tutulmalı ve cerrahi sırasında bu aparat yedek olarak bulundurulmalıdır

The inflatable penile prosthesis reservoir can be safely placed in the space of retzius after open radical retropubic prostatectomy through a penoscrotal transverse incision

OBJECTIVE: The traditional placement area of three-pieces inflatable penile prosthesis (3pIPP) reservoir is the space of Retzius (SOR) below the transversalis fascia. Likelihood of developing of fibrosis after previous pelvic surgery may be a challenging factor that can make difficult to place reservoir in the SOR. We reviewed our experience to address potential complications and safety concerns regarding the placement of the penile prosthesis reservoir in the SOR using transverse scrotal incision. MATERIAL and METHODS: Of the 122 consecutive patients underwent 3pIPP placement from 2010 to 2017, 39 had a history of open radical retropubic prostatectomy (ORRP) for localized prostate cancer (PCa) (ORRP group). Of these patients, 7 were placed MS-LGX, 18 were placed AMS-700 CX, and 14 were placed Coloplast Titan device using penoscrotal incision. Eighty-three patients had no history of ORRP (Non-ORRP group). Six patients were placed MSLGX, 19 were placed AMS-700 CX, and 58 were placed Coloplast Titan device using penoscrotal incision. The groups were compared in terms of demographic characteristics, intraoperative findings, and postoperative follow-up data. RESULTS: The mean ages of the ORRP and Non-ORRP groups were 62.2±6.5 and 58.6±9.5 (p=0.06); the mean surgery times were 57.2±11.3 and 56.7±5.3 min (p=0.32); the mean follow-up periods were 58.7±36.9 and 50.1±27.5 months (p=0.33), respectively. Mechanical failure in one patient (2.6%) and prosthesis infection in one patient (2.6%) was observed in the ORRP group. In the Non-ORRP group, reservoir dislocation due to inguinal hernia in a patient (2.6%), mechanical failure in three patients (3.6%), and prosthesis infection in a patient (1.2%) was observed. The mean postoperative treatment satisfaction rates (EDITS) were 86.8±11.3 and 85.8±12.2 in ORRP and Non-ORRP groups, respectively (p=0.91). CONCLUSION: With low complication rates, 3pIPP with its reservoir can safely be placed in patients with a history of open radical prostatectomy using penoscrotal incision. Rarely, ectopic reservoir placement is required, and this apparatus should be available at the time of surgery.
