How to DSolve this differential equation?


How can I find h(r) from this equation?
I need h(r) or its r derivative.

(E^(Derivative(1)(h)(r)^2/(2*b^2))*Sqrt(r^4*Sin((Theta)())^2)*
(-(r*Derivative(1)(h)(r)^2*Derivative(2)(h)(r)) - 
b^2*(2*Derivative(1)(h)(r) + r*Derivative(2)(h)(r))))/
(4*b^2*Pi*r) == 0

In fact, the output of Mmais kind of vague. Is there anything wrong?
