Video Telescopic Operating Microscope (VITOM) Versus Loupe- Assisted Varicocelectomy
Comparative Study Between Video Telescopic Operating Microscope (VITOM) and Loupe- Assisted Varicocelectomy (Randomized Controlled Trial)
This study aims to compare the efficacy, outcome and surgeon satisfaction in Video Telescopic Operating Microscope (VITOM) microsurgical subinguinal varicocelectomy with Loupe- assisted subinguinal varicocelectomy.

Detaljert beskrivelse
Varicocele is a common medical condition characterized by abnormal dilation and enlargement of the scrotal venous pampiniform plexus, which drains blood from the testicles resulting in complex network of swollen regurging veins.
There are different approaches in varicocelectomy; open surgical inguinal , subinguinal or intrascrotal ,which can be conventional open surgery or by using surgical microscope or Video Telescopic Operating Microscope (VITOM) or Loupeassisted. Also varicocelectomy can be done by laparoscopic retroperitoneal abdominal ligation of gonadal veins or endovascular approach using antegrade sclerotherapy. Improved semen parameters and fewer complications are noticed, when magnification has been used. Magnification can be done using surgical microscope or VITOM or Loupe-assisted.

Tidsramme |
|---|---|---|
|
Total Motile Sperm Count
Tidsramme: 3 months after surgery
|
Total motile sperm count (TMSC), expressed as millions of motile sperm per ejaculate, will be assessed by semen analysis. TMSC will be calculated by multiplying semen volume (mL) by sperm concentration (million/mL) and the proportion of motile sperm. |
3 months after surgery

Tiltaksbeskrivelse |
Tidsramme |
|---|---|---|
|
Scrotal Pain Intensity
Tidsramme: 3 months after surgery
|
Scrotal pain will be assessed using the Numeric Rating Scale (NRS), ranging from 0 (no pain) to 10 (worst imaginable pain). Higher scores indicate greater pain intensity. |
3 months after surgery
|
|
Scrotal Swelling
Tidsramme: 3 months after surgery
|
Number of participants with scrotal swelling will be assessed by clinical examination. |
3 months after surgery

Surgeon Satisfaction With the Visualization Device
Tidsramme: Immediately after surgery (with in one hour)
|
Surgeon-reported assessment using the protocol's 13-item questionnaire covering image quality, equipment handling, ergonomics, and educational usefulness. Each item is rated on a five-point scale. |
Immediately after surgery (with in one hour)
|
|
Erectile Function
Tidsramme: 3 months after surgery
|
Erectile function will be assessed using the five-item International Index of Erectile Function (IIEF-5). As presented in the protocol, total scores range from 5 to 25, with higher scores indicating better erectile function. |
3 months after surgery
|
|
Serum Total Testosterone
Tidsramme: 3 months after surgery
|
Serum total testosterone concentration will be measured by laboratory testing and compared between treatment groups. |
3 months after surgery

|
Varicocele Recurrence
Tidsramme: 3 months after surgery
|
Number of participants with recurrent varicocele will be assessed clinically at follow-up, with scrotal duplex ultrasonography performed at 3 months. |
