Crispín V. INFLUENCE OF DVH IN URINARY COMPLICATIONS IN PROSTATE LDR BRACHYTHERAPY
- 88 patients without
any urinary
complication
- 26 bladder catheter
over 2 weeks (13) or
trans-urethral
resection procedure
(TURP) (13),
DVH: urethral D1
(Dose to 1%), D10,
D30, D50, prostate
V100 and V150, and
mean urethral dose
The difference between urethral D1 and D50 “index C
1-50
”, is lower in cases with complications (p= 0.009)
With values over 37.5Gy, only 2 cases developed complications out of 28 (7.1%).
With differences <20.7Gy, 10 / 18 (55.6%) required long-time bladder catheter or TURP.
An index C
1-50
<20.7Gy is correlated with urethral complications. During the real-time procedure, a higher
difference between D1 and D50 can decrease the risk of urethral complications during the follow-up.
