Background: Undescended testes (UDT) is a condition where one or both testes is absent in the scrotum. The general age recommendation in which the treatment should be performed is before 18 months old due to the infertility risk and malignancy in later life. In post-pubertal UDT, the current guideline recommends orchiectomy; however, the strength rating of this recommendation is weak.

Pelvic-ureteric junction obstruction (PUJO) is a common condition, and one of the lead causes of hydronephrosis in children. Currently, the gold standard treatment of PUJO is open surgery using the Anderson-Hynes-modified dismembered pyeloplasty technique. However, with the advancement of medical technology, several minimal invasive approaches were developed, including endoscopic, laparoscopic, and robotic approach, from which the best choice of surgical technique was yet to be determined.

Background: Management for male infertility can be difficult for some cases. Surgical intervention has long been thought as the last resort to help married couples to conceive. The current guideline recommends testicular sperm extraction with micro-surgery technique (microTESE) in severe cases of male infertility.

Introduction: Varicocele is one of the most common treatable causes of male infertility. However, the decision to perform varicocelectomy before starting a fertility program remains controversial. This study aimed to thoroughly review and analyze the benefit of varicocele repair and its impact on the success rate of a fertility program.

The decision for using supine or prone position in percutaneous nephrolithotomy (PCNL) is still debatable. The aim of this study is to compare the efficacy and safety profile of the supine and prone position when performing PCNL. A systematic electronic search was performed using the database from MEDLINE, Cochrane library and Google Scholar from January 2009 to November 2019.

Accumulating evidence has shown that intracrinology in prostate cancer (PCa) has a pivotal role in survival of cancer cell. PCa cells are able to produce androgens from different androgen precursors, such as dehydroepiandrosterone, thereby maintaining androgen receptor signaling. Several drugs have been developed that target intracrinology, some of which are now being used as standard treatment for the so-called castrate-resistant prostate cancer (CRPC) patients.

Synopsis of recent research by authors named "William Tendi"

  • - William Tendi's research primarily focuses on male reproductive health and urological conditions, emphasizing treatment options for undescended testes, male infertility, and pelvic ureteric junction obstruction.
  • - His systematic reviews and meta-analyses highlight the effectiveness of various surgical interventions, such as microTESE for non-obstructive azoospermia and varicocele repair, in improving fertility outcomes.
  • - Recent findings suggest a need for updated treatment guidelines, particularly in post-pubertal management of undescended testes and the comparative effectiveness of surgical positions in percutaneous nephrolithotomy, indicating ongoing debates in these areas of urology.
