Abstract Background Renal calyx diverticulum refers to a cystic lesion covered with the transitional epithelium in the renal parenchyma. Although there is no clear evidence that calyx diverticulum can cause hypertension, there exists a close association between the two, and there are few related reports. Herein, we reported the case of a child with renal calyx diverticulum complicated with hypertension and summarized the diagnosis and treatment. Case presentation Physical examination of the patient, an 11-year-old child, revealed a left renal cyst with hypertension (155/116 mmHg). There were no related symptoms. Routine urine and blood biochemical examinations showed no abnormalities. Imaging revealed left renal cyst compression causing the hypertension. She underwent renal cyst fluid aspiration and injection of a sclerosing agent into the capsule, but her blood pressure increased again 3 days postoperatively. Color Doppler ultrasonography showed that the size of the left renal cyst was the same as that preoperatively. To further confirm the diagnosis, cystoscopic retrograde ureteropyelography was performed to confirm the diagnosis of renal calyx diverticulum. Subsequently, renal calyceal diverticulum resection and calyx neck enlargement were performed. The operation went smoothly and the blood pressure returned to normal postoperatively. No abnormalities were noted at the 7-month postoperative follow-up. Conclusion There exists an association between renal calyx diverticulum and hypertension. Therefore, hypertension can be considered a surgical indication for renal calyx diverticulum. Moreover, renal calyceal diverticulum in children can be easily misdiagnosed as a renal cyst. Therefore, it is important to be vigilant to prevent a series of complications, such as postoperative urine leakage, in such cases.

Objective: The prone position for percutaneous nephrolithomy (PCNL) has been widely practiced. There has been a shift from prone position to supine position which showed numerous benefits. The aim of our study is to describe the 5 year experience from the perspective of a tertiary care center using a modified Galdakao supine Valdivia position for total tubeless ultra mini supine PCNL, total tubeless supine PCNL, tubeless supine PCNL, and standard supine PCNL. Material and methods: We retrospectively reviewed the data of 90 patients who underwent supine PCNL at the tertiary care center during the period of 5 years from January 2017 to January 2021. The data collection was done from patients’ medical records. Pre operatively, complete examination of the patients with laboratory investigations were done. The modified Clavien classification system was used to classify the perioperative complications of PCNL. Results: Operative time was lowest for ultra mini supine PCNL (50 ± 10.4 min) compared to standard supine PCNL (58 ± 11.2 min). Stones were single in 54 patients and multiple in 40 patients with 4 patients with staghorn stones. The size of the stones in the largest dimension ranged from 1.2 to 5.5 cm.Complete clearance was achieved in 84 (89.7%) patients. Seven patients (7.2%) developed mild fever and four patients (4.5%) required blood transfusion. Conclusion: We found supine PCNL to be an immensely convenient, time-saving practice, and with higher stone free rate compared to prone PCNL. The different techniques of supine PCNL were also useful in patients with horseshoe kidney and calyceal diverticulum which resulted in good outcomes in these patients.

We report a complex cystic renal lesion in a 34-year-old man who presented with haematuria. It was managed by laparoscopic radical nephroureterectomy as it mimicked urothelial carcinoma.

Calyceal diverticula and epidermal cysts are extremely rare kidney lesions with unknown etiology and pathogenesis. They have non-specific clinical and radiological picture. Despite the benign nature, sometimes these disorders mimic malignant tumors leading to unjustified nephrectomy. We present a clinical and morphological observation of a multicystic lesion in a 76-year-old patient's right kidney filled with keratinized masses and imitating a malignant solid tumor. The detailed gross, histological and immunohistochemical (desmin, cytokeratin 7, uroplakin and p63) analyses of the kidney tissue excluded the malignant nature of the lesion. The final differential diagnosis was between an epidermal cyst and calyceal diverticulum with pronounced squamous cell metaplasia of urothelium. The upper pole localization of the lesion, its connection with the pelvicalyceal system through the unobstructed isthmus, the presence of urothelial lining and smooth muscle cells in its wall let us diagnose a calyceal diverticulum type I. Knowledge of the key clinical and morphological features of epidermal cysts and diverticula of the pelvicalyceal system will help the practicing physicians suspect the benign nature of such lesions and perform organ-preserving operations.

Calyceal diverticulums are often benign and asymptomatic. On the other hand, some interventions are necessary in several symptoms. Radiological imaging is performed to made dianoses, but somehow can pose misinterpretation of radiological imaging results and mistreatment from the urologist. To present a case of a calyceal diverticulum treated with open diverticulectomy. This study reported a case of a calyceal diverticulum in a 30-year-old man with an almost 1-month history of left flank pain. The patient undergone several imaging diagnostics, before finally diagnosed calyceal diverticulum with a stone inside it. The patient had underwent open diverticulectomy. Initially, cystoscopy and insertion of Double J Stent (DJ Stent) were done, and then using the lumbotomy approach the incision that had been made. This case demonstrated the use of imaging combined with urologist interpretation and surgical management which was successfully treated the patient’s clinical problems.

Renal calyceal diverticulum are outpouching from renal calyx or pelvis into the renal cortex lined by transitional cell epithelium. We report a case of 35 years old male with history of accidental fall from bike, who presented with persistent right loin pain and hematuria. CT Urogram showed multiple large right renal cysts (BOSNIAK II). Patient was planned laparoscopic renal cyst deroofing. Due to suspicion of calyceal diverticulum, an intraoperative Retrograde Pyelogram (RGP) was done which showed calyceal diverticulum. Laparoscopic calyceal diverticulotomy with closure of communication was done. If only a cyst deroofing was done considering the CT finding alone, it would have ended up in post-operative complication of urinoma which may require a re-surgery. This case report emphasizes the importance of anticipating calyceal diverticulum and intraoperative attempts in the form of doing RGP to identify calyceal diverticulum which mimic renal cyst regardless of CT finding in suspected cases. Keywords: Calyceal diverticulum; large renal cyst; retrograde pyelogram; laparoscopic calyceal; Diverticulotomy.
