Background:Testicular torsion is a common cause of acute scrotum and is complicated by loss of testes. Local data on testicular torsion is limited. This study therefore aimed at determining the incidence and clinical presentation of patients with testicular torsion in our setup.Methods: This retrospective study reviewed files of 90 patients admitted to our hospital with diagnosis of testicular torsion from January 2011 to December 2015.Results: The mean age of presentation was 19± 6 years. Fifty-nine (66%) of the patients presented with right sided torsion while 5 (6 %) had bilateral torsion. Acute, intermittent and missed types of torsion were seen in 59 (66%), 19 (21%) and 12 (13%) respectively. The duration of symptoms from onset tosurgery was 17± 4 hours. The testis salvage rates for
acute and intermittent torsion were 18% and 21% respectively. Conclusion: Testis salvage rates were lower in our setup compared to other studies. This could be due to delays in presentation and in diagnosis. Therefore, a high index of suspicion should always be maintained in all cases of acute scrotal pain.

Testicular torsion results from twisting of the vessels supplying the testes with resultant ischemia (1) It is described as acute or intermittent based on the timing of presentation (2). When a patient presents with symptoms for less than 24 hours, it is referred to as acute torsion (2, 3). On the other hand, intermittent torsion is characterized by recurrent scrotal pain caused by intermittent torsion and detorsion of the testis (4). No definitive test is available for intermittent torsion (5). The diagnosis of missed testicular torsion is made preoperatively on ultra sound or confirmed retrospectively during scrotal exploration (5). Management of testicular torsion involves detorsion of the testes and orchidopexy (1). Salvage rates are governed by speed of diagnosis and treatment. Delay in diagnosis or treatment can result in non-viable testes, this is described as a missed torsion (6).
This retrospective descriptive study was carried out at the Coast General Hospital in Kenya.This is a tertiary
population of 3 million people (7).The hospital is staffed with emergency department medical officers surgical residents and consultant surgeons including two urologists. The initial diagnosis of testicular torsion is made by medical officers and thereafter the patients are handed over to the surgical team for definitive management. Surgery is done by the consultant surgeons assisted by the surgical resident. The patient is subsequently followed up at the surgical clinics manned by both the residents and surgeons (8). We reviewed the files of all the patients presenting to the hospital with testicular torsion from January 2011 to December 2015. We excluded patients with incomplete data. The variables collected included: patient’s age, duration of symptoms from onset to surgery, intraoperative findings as to whether the testes were salvageable or not and whether surgery was done as an elective or emergency procedure. Data collected were analyzed using Microsoft Excel spread sheet.Ethical approval was obtained from the hospital ethics and review board.
Ninety patients over a five-year period were identified from the hospital registry and their files retrieved. The mean age of presentation was 19± 6 years, with a peak incidence between 11 – 21 years (Figure 1).
Figure 1: Distribution of testicular torsion with age
Fifty-nine (66%) of the patients presented with right sided torsion while 5 (6%) had bilateral torsion. The rest had left sided torsion. Acute, intermittent and missed types of torsion were seen in 59 (66%), 19 (21%) and 12 (13%) respectively. The duration of symptoms from onset to surgery was 17 ± 4 hours for acute torsion while that for intermittent and missed torsion 19 ± 14 days. All 59 cases of acute torsion and 2 (16%) cases of missed torsion underwent emergency surgeries. The rest (10 cases of missed torsion and all cases of intermittent torsion) underwent elective procedures. The testis salvage rates for acute and intermittent torsion were 18% and 21% respectively. None of the patients with missed torsion had salvageable testes. Sixty-five (72%) patients required orchiectomy. A salvage rate of 18% was achieved in the patients with acute torsion.
Age at presentation was 19 ± 6 with a peak incidence of 11 to 21 years. This is comparable to previous studies (2, 9). A study conducted in a similar setup found a mean age of 17years (1) which is similar to our findings. Testicular torsion is found mostly in men of less than 25 years with an incidence of 1 in 4000 (10). This presentation in young adult males is thought to be due to impulsive contraction of the cremaster muscles and developmental changes occurring in puberty such as increased weight of the testes (3). Presence of an attachment of the tunica vaginalis higher than normal in what is known as a bell clapper deformity is believed to further increase susceptibility in this age group (10, 11). Multiple cases have been documented in literature of testicular torsion in the same family through generations but no mutations have been proven to be responsible (12). Most patients in our setup present with right sided torsion 66%, with bilateral torsion seen in 6 % of the patients. This is departure from available literature which reports a left sided predominance (12, 13,). No literature could be found on anatomic or embryological reason for this. Further research is required to establish the true predominance. The number of patients in this study was also small (n=90) which may contribute to the variance.Acute testicular torsion was the most common presentation in patients presenting at our facility at 59 (66%) patients. A similar study conducted in the same setup found 42 patients with acute torsion over the course of 12 years (1). The increased number of patients identified with acute torsion stems from increased awareness created by the preceding study as the findings were made public following publication of the study. Statistics comparing the three types of torsion is unavailable, incidence o
