|Condition or disease||Intervention/treatment||Phase|
|Varicocele||Procedure: Combined Microscopic Varicocelectomy Procedure: Inguinal and Subinguinal varicocelectomy||Not Applicable|
The sample is selected from the patients who were referred to our center for surgical treatment of varicocele. Most of them were diagnosed after being evaluated for infertility.
All of them were operated by a single experienced and expert microscopic surgeon.
Informed consent is received from all of the possible candidates in accordance to national and Declaration of Helsinki guidelines.
Selection of patients for undergoing Combined varicocelectomy was done during the operation due to the nature of including criteria.
In this method after making an incision at inguinal level, veins are evaluated and if the including criteria is existed, only external spermatic vein is ligated at the depth of the inguinal canal and other veins are left alone for prevention of damage to the artery. Then another mini incision is made at high inguinal level and the rest of surgery is conducted by retroperitoneal approach.
The incidence rate of major complications (recurrence, testicular atrophy, hydrocele) of experimental group is compared to the incidence rate of the same complications of the patients in control group that were operated with currently common inguinal and subinguinal microscopic varicocelectomy accompanied by testicular delivery, an approach that is suggested by Goldstein and associates.
The study hypothesis is that using this method will lead to less major complications including recurrence, hydrocele and also less incidental injuries to the arteries that will result to less testicular atrophy.

Experimental: Combined Microscopic Varicocelectomy
Patients in this arm were operated with Combined Mini-incision Microscopic approach
Procedure: Combined Microscopic Varicocelectomy
After making a mini-incision at inguinal level, veins are evaluated, and if the including criteria (Complexity and tortuosity of the veins and/or existence of veins that are contiguous with arteries so that separating and ligation of the veins could jeopardize the artery) are existed, only external spermatic vein, if dilated, is ligated at the depth of the inguinal canal, and other veins are left alone for prevention of damage to the artery. Subsequently, another mini-incision is made at high inguinal level and the rest of surgery is conducted by retroperitoneal approach, which is also done microscopically
Active Comparator: Inguinal and Subinguinal Varicocelectomy
Patients in this arm have the same including criteria as Experimental arm but they were operated with conventional and currently popular approach of Microscopic Inguinal and Sub inguinal varicocelectomy suggested by Goldstien and associates
Procedure: Inguinal and Subinguinal varicocelectomy
Microscopic Inguinal and Sub inguinal varicocelectomy, recommended by Goldstein and associates, are currently popular approaches. In this approach the spermatic cord structures are pulled up and out of the wound so that the testicular artery, lymphatics, and small periarterial veins may be more easily identified. In addition, an inguinal or subinguinal approach allows access to external spermatic and even gubernacular veins.
- Recurrent Varicocele [ Time Frame: 6 months ]post-varicocelectomy recurrence is measured by physical exam at intervals of 10 days,3months and 6months after surgery
- Post-varicocelectomy Hydrocele [ Time Frame: 6months ]Development of hydrocele is assessed by physical exam at intervals of 10 days,3months and 6months after surgery
- Post-varicocelectomy Testicular Atrophy [ Time Frame: 6months ]development of testicular atrophy is assessed by physical exam at intervals of 3 and 6 months after surgery
