Robotic surgery can be a treatment option but there are other treatments too like medications, lifestyle changes etc. Based on the severity of your condition, and after seeing the reports physically, the best treatment for you can be decided. 

More detailed history and tests like Uroflowmetry and Ultrasound with Post void residual measurement will give accurate diagnosis. If it’s BPH only and not improving with medicines then might need a surgical treatment. There could be other reasons like urethral stricture or high bladder neck which is also dealt surgically.

If you're experiencing pain, redness, or swelling in your penis, it's important to see a doctor for evaluation and treatment. While waiting for the appointment, keep the area clean, avoid further irritation, and don't try to pop any bumps. Consider any recent changes in products you've used.

If you are going through an itchy penis, you should refer a urologist or a dermatologist with a specialization in genital conditions. They will be able to diagnose you properly and suggest the best treatment for you. It is advised to consult a physician instead of self-diagnosing and applying home remedies.
