Acute urinary retention is one of the most common situations encountered in urological emergencies. It is more frequently seen in older men. Acute urinary retention in pregnant women is a rare condition but it may cause abortus, preterm labor and rarely uterine ischemia. It is very difficult to reveal the causes of acute urinary retention in pregnant women. One of them is acute urinary retention due to retroverted uterus which is observed in 11% of pregnant women.  In this case, we discussed a young pregnant patient who presented to our outpatient clinic.

Primary or secondary lymphoma of the prostate is a rare condition. Mantle cell lymphoma (MCL) represent 4-9% of all lymphomas. Prostate involvement with MCL is very rare, with only 11 reported cases up to now. Here we present a case with lower urinary tract symptoms and prostate-specific antigen (PSA) elevation diagnosed with MCL of the prostate. Prostate biopsy was performed in a 70-year-old patient due to increased PSA. After the pathology result was reported as prostatic MCL, imaging studies and sampling of additional pathological specimens were performed for staging.

Immunosuppressive therapy is related to the increasing frequency of malignancies after transplantation. A small percentage (4.6%) of malignancies seen in kidney transplant patients are renal cell carcinomas (RCC) which occur almost exclusively in native kidneys. The prognosis of RCC largely depends on the presence of metastasis. Metastatic disease is very rare in small renal masses. In this case report, we aimed to present our case of approximately 4 cm-mass of metastatic RCC in our kidney transplant patient.

In the evaluation of a 32-year-old male patient who was referred to our clinic with the complaint of gynecomastia and primary infertility, ennuchoid structure, hypergonadotropic hypogonadism, and azoospermia were detected. Based on these findings, the genetic evaluation revealed the presence of 48XXYY syndrome. In this case report, we aimed to report the diagnostic algorithm and management of 48 XXYY syndrome. It should be noted that fertility should not be expected in patients with 48XXYY syndrome.
